function.session-save-path Error Cache Folder was 170mb!!

Ok so this morning our website went offline due to us exceeding our bandwidth, which i found strange got the site back online now it appears the Cache folder was the culprit.

The cache folder is full or error logs saying the same error:
[22-Aug-2011 12:43:51] PHP Warning: session_save_path() [<a href='function.session-save-path'>function.session-save-path</a>]: Unable to access /var/www/vhosts/yorkshiregardencentre.co.uk/httpdocs/shop//cache in /var/www/vhosts/silicalodgegardencentre.co.uk/httpdocs/shop/includes/functions/sessions.php on line 168

We moved domains in January 2011, I have tried the fix cache key untiity but i get a error in firefox and page cannot be displayed in IE.

Ive checked both confiqure.php files in admin and includes and both have the correct path also checked the database SESSION_WRITE_DIRECTORY and that also has the correct term of:
/var/www/vhosts/silicalodgegardencentre.co.uk/httpdocs/shop/cache

So why is this error still happening

Thanks in advance for your help guys!

You must be checking the wrong database table.

I checked the configuration table for the entry:
SESSION_WRITE_DIRECTORY

I assume this is correct?

There are 3 places where that value is set:
- 2 configure.php files: DIR_FS_SQL_CACHE
- configuration table in database SESSION_WRITE_DIRECTORY

If you're encountering PHP errors that are showing that the system is trying to write session or cache data to some invalid path, then one of those 3 settings contains incorrect data.
And, if you've checked all those 3 settings, then either you're not looking at the data actually ON the server, or you're looking in the wrong database or wrong table. Remember, if your site is set up to use table prefixes (DB_PREFIX other than '') then you need to look at the table whose name starts with that prefix.
