Error when installing/discovering new template

[vrieskist]

Ok, so I tried to make my own template, very basic just a skeleton. But it failed to install in the discover screen. After that I tried to duplicate a default template, change the folder name, change the name in the templateDetails.xml. This also gave the same error:

Code: Select all

Notice: Undefined variable: lang in /Users/username/Sites/sitename/libraries/joomla/installer/adapters/template.php on line 543 Fatal error: Call to a member function setDebug() on a non-object in /Users/username/Sites/sitename/libraries/joomla/installer/adapters/template.php on line 543

I'm running Joomla 2.5 on my local machine (OSX 10.7) with Apache 2, PHP5, MySQL5. I'm pretty new with Joomla, but pretty experienced in web development, but I couldn't find a solution for this problem.

Ok, quick addition!
Installing the theme from a directory in the Extension Manager: Install works. So the problem is in the Discover function for installing a template. I would still like to know if this is a known bug or something.

I have the same issue.

Yesterday version 2.5.3 my custom template worked fine.

Today version 2.5.4 custom template now won’t work.

I have also tried duplicating one of the templates which come with Joomla as standard and renaming it, this also returns the same error. I have tried it on my local Windows 7 machine and on a live server, again same errors.

Discovery work fine, it is only when I try to install that I get the error.

Fatal error: Call to a member function setDebug() on a non-object in C:\xampp\htdocs\Joomla2.5\libraries\joomla\installer\adapters\template.php on line 543 (local machine)

Fatal error: Call to a member function setDebug() on a non-object in /home/evowebst/public_html/joomla/joomla2.5/libraries/joomla/installer/adapters/template.php on line 543 (Live server)

what have I missed? have I done something wrong? is it a bug with 2.5.4?

any help would be much appreciated.

thanks

[goslingcools]

Same error here too. (Joomla 2.5.4)

Code: Select all

Fatal error: Call to a member function setDebug() on a non-object in ... libraries/joomla/installer/adapters/template.php on line 543

Did you guys find a solution for this?

[vrieskist]

Don't have the solution yet.

I found a workaround by installing the theme 'from directory' in the 'Extension Manager: Install' screen.

[goslingcools]

I was discovering & installing a custom J1.5 Template into a plain J2.5 site.

To get it to work, I adjusted the templateDetails.xml file to the J2.5 syntax. Zipped the template and did a normal extension install.

That worked.

[arielmorry]

go to libraries/joomla/installer/adapter/template.php
comment out lines 543 and 558 > discover and install your template > un-comment those lines back.

worked for me on joomla 2.5.4.

//$lang->setDebug($debug);
//$debug = $lang->setDebug(false);

good luck

[goslingcools]

Thanks but I never change the Joomla core code. Just use overrides and (custom) extensions.
This makes updating (many) sites easy, safe and keeps them stable :-)

[arielmorry]

temp change:
"un-comment those lines back".

Could you provide a link to the J2.5 template syntax? Because I think I have the template in the correct format.

The uncommenting 'fix' could work for at least installing one template and that could be enough, but is not a lasting/durable solution.

[goslingcools]

This is what I used. Very basic.

Make sure that the <name> is the same as your template folder (for example mytemplate_tpl)

Never mind the install PUBLIC "-//Joomla! 1.6/, that worked fine with me.

Code: Select all

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE install PUBLIC "-//Joomla! 1.6//DTD template 1.0//EN" "http://www.joomla.org/xml/dtd/1.6/template-install.dtd">

The error message "Undefined variable: lang in .../libraries/joomla/installer/adapters/template.php on line 543" is caused by a bug in the Joomla code. It only exists in version 2.5.4.

The variable $lang has not been correctly initialised in the function "discover_install()" in the file mentioned above.

The bug has been reported fixed for the next release and is detailed here: http://joomlacode.org/gf/project/joomla ... m_id=28345

The fix, as outlined in the bug report is to add the line "$lang = JFactory::getLanguage();" to the installed Joomla code like this:

Code: Select all

...
	public function discover_install()
	{
		$lang = JFactory::getLanguage();
		// Templates are one of the easiest
...

Obviously you should only do that if you're confident and sure you know what you're doing. Make backups, before attempting it.

Hope that helps!

Tom

This also worked for me. Thanks for posting this info, it saved me!

[beormalte]

Ok, so I am reading the Joomla Programming book too, and I am also having the same issue duplicating the beez template.
When ever I use the discover tool and click the install icon after appropriately copying the beez template and renaming it to beez_copy. I get this page:

The website encountered an error while retrieving http://localhost:8888/Joomla-Site/admin ... w=discover. It may be down for maintenance or configured incorrectly.

I know that all the files have been changed correctly because I have downloaded and used the finished sample from http://joomlaprogrammingbook.com/images ... 0_copy.zip .

I also copied the language files in the /language/en-GB directory.

So any ideas anyone?

[beormalte]

Joomla Apprentice has it right :-)

go to libraries/joomla/installer/adapter/template.php
comment out lines 543 and 558 > discover and install your template > un-comment those lines back.

worked for me on joomla 2.5.4.

//$lang->setDebug($debug);
//$debug = $lang->setDebug(false);

good luck

[ChrisRArendt]

Thanks everyone for the help. The code change fix worked for me and was relatively straightforward. Since this is slated to be fixed I figured it was an okay change to make.

[Freddy63]

un-commenting did the trick thanks!

[fbcyborg]

Hello,

I had this problem too after a migration from Joomla! 1.5 to Joomla! 2.5.
This is the error message:

Fatal error: Call to a member function get() on a non-object in /var/www/localhost/htdocs/website/jupgrade/templates/beez_20/index.php on line 119

Joomla Apprentice has it right :-)

worked for me on joomla 2.5.4.

//$lang->setDebug($debug);
//$debug = $lang->setDebug(false);

good luck

The above trick didn't work for me.
What to do?


EDIT: solved. I forgot to change dbprefix to j25 after migration

Thanks Tom for this, It helps

I have many of these problems!
Please introduce a resource that would help in the installation and update Joomla Templates
