here is what i got
==========================

Warning: dir() has been disabled for security reasons in /home/shaqrage/public_html/rc/program/include/rcube_plugin_api.php on line 112

The function dir is disabled on your server, it needs to be removed from disable_functions in the php.ini file. If you don't have access to the php.ini file you'll have to ask your hosting provider to remove it for you.

well how come i can access roundcube from cpanel then ?:confused:

[SKaero]

They could be using an older version of RoundCube or have it enabled just for cPanel.
