Migrated from 1.0.13 to 1.0.15.
Server handled directly not by an ISP.
If I use Firefox to access as admin it works perfectly.
If I use IE to access as admin I will get "Invalid Session".

Into session.save_path directory with Firefox I can see just one sess_xxxxxxxxxxx file. With IE there are two files and one it is empty.

I tried all solution without results. With IE doesn't work, with Firefox it works fine !!!

Please provide me a feedback.

If you need more informations please do not hesitate to contact me.

As I understand it (and remember, I'm a newbie!!!) PHP needs some place to store the session data. The default place to do this in in the /tmp folder of your service provider.

If you want to store the session info somewhere else (like within your own installation) you need to create a directory to put it in. I called mine "sessions" which seems to be a fairly common thing to call it, judging from the various threads about this. CHMOD the directory you created to 755 so it's writeable.

When you create your custom PHP.INI file, you need to make sure that the path/to/your/Joomla installation is the "absolute path" used by your service provider. You'll find a copy of that in your CONFIGURATION.PHP file -- look for the line that reads

$mosConfig_absolute_path =

The absolute path is everything inside the quotation marks.

Careful of typos -- even one letter wrong means the thing won't work at all!

Hope that helps

To recap here is what I did.

1. I created a /sessions/ directory in /public_html/web/

Where web is my directory where joomla was.

2. Create a two line php.ini

With the following two lines.

session.save_path = /full link to your account/public_html/web/sessions
register_globals = OFF

where /full link to your account/ is what is the absolute path in your configuration.php file.

3. PUt the php.ini file at the root of the administrator directory in

/public_html/web/administrator

Voila!

It worked. Man this was a time sinker.

Where would the world be without 'google' and 'forums'!

Scary!

Thanks for all the suggestions.

go to line 770
and change line

Code: Select all

if ($session_id != session_id()) {

to

Code: Select all

if ($session_id != $session_id) {

mind the $ and the () around session_id

This will do the "if" check on an "a" compare to "a" basis, which will work ofcourse

Like I said it's a hack and I will still hope the joomla guys will say something smart about this.

Cheers,

Step 1. Create a new folder called tmp at root (same level as /public_html)

Step 2. Create a text file (using notepad or a text editor) with the following code:
session.save_path /(root directory)/tmp
Note: you will find your root directory at: /public_html in the configuration.php file on line 6 $mosConfig_absolute_path =.....

Step 3. Save as php.ini on your desktop

Step 4. Using your ftp program, transfer the php.ini file that you have just created into your new folder which you called tmp.

That worked for me.

Code: Select all

/*if ($session_id != session_id()) {
			// session id does not correspond to required session format
			echo "<script>document.location.href='index.php?mosmsg=Invalid Session'</script>\n";
			exit();
		}*/

If your host is running php as apache module just add this two lines in your .htaccess file:

Code: Select all

php_value session.save_path '/your_joomla_root_diretory/session'
php_value session.auto_start 0

Of course make a writable 'session' directory in your joomla root with permission 777

If php is running as CGI binary, create a local php.ini in your document root directory and add the below lines:

Code: Select all

session.save_path = /path_to_your_session_direcory
session.auto_start = 0

This worked for me and I hole it helps.

Thanks

sfetter wrote:Hi folks

I too have struggled with the Invalid Session problem ... and I think I have finally found something that works for my site.

I think that if PHP_Register_Globals is OFF (which is the recommended safer way to run the system), then my service provider wasn't saving the session data in the default file (which /tmp). Even though "System Information | Permissions" showed that /tmp was WRITEABLE, I now suspect that something in my service provider's setup made this unreliable.

(Come to think of it ... /tmp is a public directory on my service provider. Anybody can write to it. I wonder if somebody else's Joomla installation was also set to save session data to the same public directory ... which would mean that sometimes the session data would be stable for a while, but at other times it could have been overwritten almost immediately. That would explain why my sessions would last variable amounts of time.)

When I created a "sessions" directory within my own installation of Joomla, and put instructions re this in my php.ini file FIRST (before the direction to turn off register_globals) I stopped having problems all together.

To be clear, here's my php.ini file now. I have a copy in my main directory, and another copy in my administrator directory:

session.save_path=/path/to/joomla/sessions
register_globals = OFF
