email is working fine for users who connect with other software, but when trying to log on using the web interface users are confronted with Invalid request! No data was saved.
On checking the error log the line below is shown:
[20-Aug-2015 20:02:46 Europe/London] PHP Warning: session_start(): Cannot find save handler 'memcached' - session startup failed in /usr/share/psa-roundcube/program/lib/Roundcube/rcube_session.php on line 117
memcached is installed and running correctly on this server, I also noted that since the software updated there is no session data being saved to the db.
Any hints or suggestions would be warmly welcomed.
