Hi
I would be most grateful if someone could comment/help with the following:
I am getting 'Invalid token' messages when logging into the back end of one of my sites (Contao ver 2.11.17).
Upon investigation of the error logs I see
"PHP Warning: Unknown: write failed: No space left on device (28) in Unknown on line 0" followed by
"PHP Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct () in Unknown on line 0"
I have contacted my hosting provider and have confirmed that there is plenty of space. The site was fine 24 hrs ago when I ran some backups over the w/e.
As the session data is not saved I cannot log in to purge temp files or whatever.
Running the Check tool shows that everything seems to be OK, output as follows:
PHP 5.2.6
◦You can install Contao 2.x
◦You cannot install Contao 3.x (requires PHP 5.3.2+) (as expected)
Requirements
◦You can use the Extension Repository. More information …
◦You cannot use the Live Update. More information … (as expected)
◦You do not need the Safe Mode Hack. More information …
(with the Creating Test Folder and Test File OK and the 'Validate an installation' does not throw anything up).
..with the exception of the above two PHP warning messages below the output from Contao Check 7.15
Has anyone seen this before or have any ideas on how to try and sort this out?
Thanks.
SOLVED: on asking host provider to verify that the ‘session.save_path’ was correct, it transpired that the /var/tmp filesystem had suddenly filled which was affecting PHP's ability to write session files. Now all sorted.
