Make sure the line
Code:
LoadModule suexec_module modules/mod_suexec.so
is enabled in the httpd.conf file. Also check the apache modules directory for mod_suexec.so to make sure you have the module installed. If not you will have to install it before enabling the above line.
Once you have verified the existence of the files and uncommented the line, restart apache.
Hope this helps,
