Hello, I followed the tutorial exactly as per the Wiki for converting Apache to LiteSpeed under the DirectAdmin control panel. I also followed the small code snippets in order to make the Webmail applications work. Uebimail works flawlessly now, however even after adding the code for Squirrelmail, it still doesn't work as expected. Wiki Article: http://www.litespeedtech.com/support/wiki/doku.php?id=litespeed_wiki:apache:da Squirrelmail outputs the following. PHP: Error opening ../data/default_pref Default preference file not found or not readable! Please contact your system administrator and report this error. Any further ideas regarding this?
