Plesk: Error opening /var/lib/squirrelmail/prefs/default_pref
On brand new Plesk 8.2.x installations or on servers that have been upgraded to Plesk 8.2.x, you might run into this error when you attempt to log into squirrelmail after it was installed via RPM:
Error opening /var/lib/squirrelmail/prefs/default_pref Could not create initial preference file! /var/lib/squirrelmail/prefs/ should be writable by user apache Please contact your system administrator and report this error.
No matter what you do to the /var/lib/squirrelmail/prefs/default_pref file, even if you chmod 777 the file, you will still get the error. If you check the /etc/php.ini, you will normally find
safe_mode set to on.
; ; Safe Mode ; safe_mode = Off
safe_mode to off and reload Apache. If you try to log into squirrelmail again, it should complete successfully. I’ve tested this on Red Hat Enterprise Linux 4:
# rpm -q squirrelmail squirrelmail-1.4.8-4.0.1.el4
