After Upgrade from 1.65 to 1.7, frontend is not working

[Raikkonen_WC]

I just upgraded to 1.7, and it went very easy. Only problem is dat I now have a website without a loaded template. And when I select a template (beez20 for example), the website stays "Blank"...

On the frontend, I get this error:
Fatal error: Call to a member function getPath() on a non-object in /home/w0824589/domains/raymondsmits.com/public_html/joomla_new/libraries/joomla/application/categories.php on line 516


See here what I mean:
http://www.raymondsmits.com/joomla_new

How can I fix this???

Also when I go to "Global Configurations, Site" The select buttons of the options "site, system,server,premission" don't work. I then get a error underneath in IE9:

Before you begin, backup your website files and database. This is important.

I guess you took a backup before the upgrade?

[Raikkonen_WC]

Yes.. This is my test site, my normal site is still online, I'm just testing it on the background.

[Raikkonen_WC]

I just tested something. When I'm in the Menu, HOME options, and I set the #Links value to 0, the website loads, and I see the template. But when I click on one of the buttons, I get this error:

Fatal error: Call to a member function getPath() on a non-object in /home/w0824589/domains/raymondsmits.com/public_html/joomla_new/libraries/joomla/application/categories.php on line 516

[Raikkonen_WC]

I found a link on the website that would fix my problem:
http://joomlacode.org/gf/project/joomla ... m_id=26393

But how do i run this file?

[itfidds]

Hi,

You don't run the file as such - rather you need to make the changes contained in the category0fix.patch file to your original libraries\joomla\application\categories.php file.

The file category0fix.patch contains references to where the changes need to be made.

For example: -

Code: Select all

@@ -278,7 +278,7 @@
 					$this->_nodes[$result->id] = new JCategoryNode($result, $this);
 
 					// If this is not root and if the current node's parent is in the list or the current node parent is 0
-					if ($result->id != 'root' && (isset($this->_nodes[$result->parent_id]) || $result->parent_id == 0)) {
+					if ($result->id != 'root' && (isset($this->_nodes[$result->parent_id]) || $result->parent_id == 1)) {
 						// Compute relationship between node and its parent - set the parent in the _nodes field
 						$this->_nodes[$result->id]->setParent($this->_nodes[$result->parent_id]);
 					}

The

Code: Select all

@@ -278,7 +278,7 @@

above means change 7 lines starting at line 278 in categories.php and replace them with the 7 lines underneath the @@ line.

You will note that there are actually 8 lines in the patch file, but you remove the complete line that starts with - (minus) sign.

Remove the + (plus) signs too, but not the whole line!

Hope that helps.

[Raikkonen_WC]

Thanks!!!! It took a while before I could test it. But I just added all the lines and the website works! Again, thank you for the explanation!

Hi all,
I have the same bug :
Fatal error: Call to a member function getPath() on a non-object in F:\xampplite\htdocs\mysite\jupgrade\libraries\joomla\application\categories.php on line 516
I can view the backend but I've this error on the frontend.
I've tried to correct the config.php in F:\xampplite\htdocs\monsite\jupgrade\libraries\joo mla\application\categories.php with the tips you provide above.
After that, I can see my frontend but my computer need to be restarted as soon I go to my home page because of my mouse and the keys don't work.
Is there another tips to let JUpgrade work properly ?
I ask it because it seems it's a good composant and I'm near the goal...

I have to admit that your post worries me somewhat!

The original issue of

Code: Select all

Fatal error: Call to a member function getPath() on a non-object in F:\xampplite\htdocs\mysite\jupgrade\libraries\joomla\application\categories.php on line 516

is relatively easy to rectify if you modify \libraries\joomla\application\categories.php as per the posting above. If you cannot carry out the changes yourself, let me know and I will post an edited version of categories.php for you.

However, you also mention correcting config.php and there is no need to edit any files of that name. The only file that needs to be amended is \libraries\joomla\application\categories.php

Then you have problems with needing to reboot your computer because

as soon I go to my home page because of my mouse and the keys don't work

I find it hard to believe that Joomla is causing this issue and would look more towards a virus on your PC.

Lastly, I would try to avoid using IE9 to administer the back end of any Joomla site - I am currently investigating some incidences where clicking certain buttons in the administrator site does not carry out the action that the button should perform.

[Kirigol]

Hello bcoadmin,
I thank you fot your prompt answer.
I've followed the tips... And replace the 7 lines,

Code: Select all

// Create the JCategoryNode and add to _nodes
$this->_nodes[$result->id] = new JCategoryNode($result, $this);
// If this is not root and if the current node's parent is in the list or the current node parent is 0
if ($result->id != 'root' && (isset($this->_nodes[$result->parent_id]) || $result->parent_id == 0)) {
// Compute relationship between node and its parent - set the parent in the _nodes field
$this->_nodes[$result->id]->setParent($this->_nodes[$result->parent_id]);}

so now I've : (I comment all the line which begin by - (minus) and cancel the + (plus))

Code: Select all

// Create the JCategoryNode and add to _nodes
$this->_nodes[$result->id] = new JCategoryNode($result, $this);
// If this is not root and if the current node's parent is in the list or the current node parent is 0
//  if ($result->id != 'root' && (isset($this->_nodes[$result->parent_id]) || $result->parent_id == 0)) {
  if ($result->id != 'root' && (isset($this->_nodes[$result->parent_id]) || $result->parent_id == 1)) {
// Compute relationship between node and its parent - set the parent in the _nodes field
$this->_nodes[$result->id]->setParent($this->_nodes[$result->parent_id]);}

As soon I do that and what to reach the homepage my computer is frozen and I had to reboot it.
I've tried with firefox and IE

I apologize for the config.php, I was talking about categories.php in fact.
So I've run different antivirus scan on my computer, it seems everything is ok, without known viruses.

[itfidds]

OK, it's difficult to say whether your code is completely correct as there were multiple sections to amend.

I have attached a copy of categories.php that I am using on several installations of Joomla 1.7

Rename your original \libraries\joomla\application\categories.php to something like \libraries\joomla\application\categories.ori.php

Then copy the attached file to \libraries\joomla\application\
Rename it from categories.php.txt to categories.php

Logout of Joomla administator backend and login again

Let me know how you get on

[Kirigol]

Thanks a lot.
It seems I had to try a different method to migrate my site because of even with your files my CPU crash as soon as my homepage is loaded =(

[itfidds]

Curious that a homepage can make a PC crash or hang.

So are things working now?

Personally I would try not to migrate. Start with a clean install of Joomla 1.7, install required modules/components/plugins and DOCUMENT every step. Then, if necessary import your content. However, I would still rather copy and paste content and reload images rather than import. Possibly more work but it ensures a clean start and should pay dividends in the long run...

[Richnyc30]

This error developed after I deleted a couple of test modules.
Downloading the attachment above for category.php seems to be working.
Didn't have to log out.
I had thought I had a corrupted database. Thanks.

In my case it seems my computer don't support the frontend of 1.6 and 1.7 and I don't know why. I can reach the frontend with others computer. Even when I disabled all the application with msconfig.
That's all I know.

Kirigol, I have never come across a situation where a computer crashes when accessing Joomla.

You say that others (i.e. other computers) can access the frontend without problems, yet in a previous post you inferred that the site runs locally on the xamp platform

F:\xampplite\htdocs\mysite\jupgrade\libraries\joomla\application\categories.php on line 516

So if you are running xamp locally, how are others accessing your computer?

Additionally, although I am not overly familiar with xamp (I use wampserver) I notice that you appear to be using xampplite. I was under the impression that this version had been dropped some while ago. If it has been dropped then your versions of PHP and mySQL will be out of date.

Can you post answers to the above and also details of which versions of PHP and mySQL you are running?

Thanks

[Kirigol]

It seems it's a particular problem which occurs only on my computer so I've notified it because you 've tried to help me. I've searched on many support site nobody knows what happens so I will try to migrate my site with another computer.

You're right I've said I was working on a local site.
But I've tried to use wamp to, I've changed the version of xamp, I've upgraded all my PHP and SQL version with the latest server programms. It was the same, the frontend freeze my Computer.

I've tried a online installation. And it's the same the homepage frontend j1.6 and j1.7 crash even with a new install. But I can see the frontend and surf on it with other CPU (thanks to my mom and my wife). Now I can install all the joomla versions with closed eyes =)))
I've disabled all the applications with execute-->msconfig. I've uninstalled some applications.
And nothing is better. So don't bother with my trouble it comes from my computer that's it. Sorry for wasting your time.

I will try your nice composant with another computer...

[itfidds]

...And nothing is better. So don't bother with my trouble it comes from my computer that's it. Sorry for wasting your time.

Well I don't mind the time - if I can help I will and that's the beauty of the Joomla forums!

Lastly regarding the Joomla problem, are you using 32bit or 64bit PHP and mySQL? I have tried 64bit versions of both PHP and mySQL and have had problems so I have gone back to 32bit.

However, I would be concerned about your PC. Does the event log show anything just before the freeze? Maybe it's worth checking out malware/viruses? Why not pop over to http://www.bleepingcomputer.com and posting an issue there - the guys are geniuses...

[Kirigol]

The config is as following :
+ Apache 2.2.14 (IPV6 enabled)

+ all systems 32 bit (64 bit should also work)

I will ask on bleepingcomputer, is I find an issue I will keep you informed... Thanks for all...

[itfidds]

This is the current offering from wamp: -
WampServer 2.1e [07/01/11] Including :
- Apache 2.2.17
- Php 5.3.5 (version 32 bits)
- Php 5.3.4 (version 64 bits)
- Mysql 5.1.53 (version 64 bits)
- Mysql 5.5.8 (version 32 bits)
- XDebug 2.1.0-5.3-vc6 (32 bits)
- XDebug 2.1.0-5.3-vc9 (64 bits)
- XDC 1.5
- PhpMyadmin 3.3.9
- SQLBuddy 1.3.2
- webGrind 1.0

There is an equivalent download for xamp using pretty much the same versions as wampserver.

However, whilst your versions are slightly out of date, the only thing that I would question is your version of mySQL. I am sure that I was running 5.1.41 (as 64bit) which caused me problems.

Wow - I can't thank you guys enough for this thread. I reverted some k2 menu items (articles) to base joomla menu items (articles) and I got this same error out of nowhere. Could have been related to running a global check-in but honestly, I have no clue.

The proposed solution to edit file public_html/libraries/joomla/application/categories.php

and simply replace line 281 (Joomla! 1.7.0 Stable)

if ($result->id != 'root' && (isset($this->_nodes[$result->parent_id]) || $result->parent_id == 0)) {

with

if ($result->id != 'root' && (isset($this->_nodes[$result->parent_id]) || $result->parent_id == 1)) {

got me back in business instantly.

I thought I was toast and going back to a 10 hour old backup. Thanks again for taking the time to post issues and fixes.
