I have having some web server issues today. The logs said:
suexec policy violation: see suexec log for more details
The suexec logs read:
[2011-05-25 10:54:35]: uid: (10027/user) gid: (505/505) cmd: cgi_wrapper
It's possible that your SUEXEC file /usr/sbin/suexe is corrupt or invalid.
cp /usr/local/psa/suexec/psa-suexec /usr/sbin/suexec service httpd restart
