I have trying to access my emails via Horde 3rdparty tool which is pre-installed with cpanel, Now action happens when I hit login. but I can use Squirrelmail, but no error have seen in log.
After some more googling I got the solution. Please verify that (/var/cpanel/userhomes/cpanedmin/sessions/) has full privilage for user & group : cpanelhorde
1. Login to shell of the server using root login details and open the file ” /usr/local/cpanel/3rdparty/etc/horde/php.ini ” using vi or any other editor
2. Search for [Session] and change the following
session.save_handler = sqlite session.save_path =/var/cpanel/userhomes/cpanedmin/sessions/phpsess.sdb
session.save_handler = files session.save_path = /var/cpanel/userhomes/cpanedmin/sessions/
3. Save and exit
4. Restart Apache server.
