If you have cpanel server, and have phpsuexec or suphp installed and you get “Internal Server Error” message while accessing account on your server, you must see permission in users directory. If PHP runs with phpsuexec or suphp, all files under accounts must have correct ownership. If you see that your directory/account ownership still nobody, you must change it manually or you can use cpanel included scripts to repair permission for all accounts.

First, you must log into SSH, and then you can run this script :

root@server [/]# /scripts/chownpublichtmls

hope this helps

tmp can be secured to be noexec in 1 minute, no reboot required. Nothing can execute there – /var/tmp remains a risk – unless that is mounted separately also:

/dev/VolGroup00/LogVol02 /tmp ext3 defaults,nosuid,noexec 1 2

edit the /etc/fstab file, then do a mount -o remount and it will remount /tmp and you are set – just don’t be in /tmp when remounting.

This is old problem, but while netenberg not release new fantastico which supports newest cpanel release, this problem still appears.

Fantastico, the most popular auto installer  plugin for cpanel, have compatibility problem with newest cpanel release. Newest cpanel release using register_global=off for their php backend, and this not supported by Fantastico.

Since May 2008, Netenberg promises will release updated fantastico that compatible with latest cpanel release, but until now no update release from netenberg, so we must temporary fix this problem until they release.
