Sudden error appeared....

[inshallah]

One of the SC site I maintain showed these errors today:

Warning: session_start() [function.session-start]: open(/var/lib/php/session/sess_lndcg4muusle3lb89b4lprgk52, O_RDWR) failed: Read-only file system (30) in /var/www/html/squirrelcart/pre_common.php on line 177

Warning: Unknown: open(/var/lib/php/session/sess_lndcg4muusle3lb89b4lprgk52, O_RDWR) failed: Read-only file system (30) in Unknown on line 0

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php/session) in Unknown on line 0

Nothing has been changed with the site in literally years. Some pages in the CP seem to come up, but only intermittently. Maybe it's a database issue? Since it's referencing specific files I thought it might be a bug.

This is definitely not a database issue, and not a bug. Your host is having problems with session support for PHP. In order for sessions to work, PHP needs access to read AND write to the location specified as session.save_path in your php.ini file. It appears that location is read only on your server. Report it to your web host and they should be able to fix it for you.
