Blank Screen w/ RoundCube 0.9.5 - Fix

If you are upgrading your old custom build you may find that RoundCube gives you a blank page when you try to log in.

After racking my brain and searching I found the easy solution.

Even though the log will report a database issue, it's actually a permissions issue.

chmod 755 /var/www/html/roundcubemail-0.9.5 -Rf

Worked for me - maybe it'll help you too.

sometimes blank screen it's php error. like safemode, or error_reporting is disabled,

1 recommend you to remove the roundcube. and install it agian
by: rm -rf /var/www/html/roundcube*
and install by : ./build roundcube
