I'm getting that error when trying to view a simple 'hello world' perl script. stderr says: 2010-03-27 10:51:36.323 [STDERR] lscgid: execve():/home/xx/public_html/cgi-bin/perl.cgi: No such file or directory However that file exists and permissions seems okay. If I switch back to Apache, I get some useful logs: [Sat Mar 27 10:46:08 2010] [error] [client ] suexec failure: could not open log file [Sat Mar 27 10:46:08 2010] [error] [client ] fopen: Permission denied [Sat Mar 27 10:46:08 2010] [error] [client ] Premature end of script headers: perl4.cgi 2010-03-27 10:39:24.228 [STDERR] [2010-03-27 10:39:24 -0500] warn [whmredirect] User file '/var/cpanel/users/nobody' is empty or non-existent. at /usr/local/cpanel/Cpanel/Config/LoadCpUserFile.pm line 35 Cpanel::Config::LoadCpUserFile::load('nobody') called at /usr/local/cpanel/Cpanel/Config/LoadCpUserFile.pm line 158 Cpanel::Config::LoadCpUserFile::loadcpuserfile('nobody') called at /usr/local/cpanel/Cpanel/AcctUtils/Domain.pm line 16 Cpanel::AcctUtils:omain::getdomain('nobody') called at /usr/local/cpanel/Cpanel/Redirect.pm line 63 Cpanel::Redirect::redirect('service', 'whm', 'ssl', 0) called at /usr/local/cpanel/cgi-sys/whmredirect.cgi line 11 I tried it on another server and it works fine, so it's something with this server, I also have a open ticket in with cPanel. Another person here had the same error message and LS recommended increasing memory, but I don't think it's the same problem.
