Without any changes, we suddenly received the following error while wanting to access our mysql dbase via phpmyadmin:
Warning: Unknown: open(/var/lib/php/session/sess_8i4gv03ka359ktq4tp4h81oufs638cig, 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
Does anyone know why this happened & how I can solve ?
thx bart
Your problem is that your sessions directory is not writable by the web server. This disables your ability to create sessions.
First check that the directory /var/lib/php/session/ exists. If so, check if it's on a writable medium. Because the message Read-only file system makes me a little unsure.
Then make the directory /var/lib/php/session/ and its current contents writable for the web server. Try chowning the directory to the user that runs your web server. Or (easier, but a bit less secure) chmod 777 /var/lib/php/session followed by chmod 666 /var/lib/php/session/*
