Hello,

CLOUDLINUX 6.5 x86_64 installed on Cpanel 11.40.1.
cagefs version: 5.2-21
Effective kernel version is 2.6.32-458.23.2.lve1.2.48.el6
php is running as suphp

enabling cagefs for user with a wordpress site gives error 500 in browser, and error log file shows:

SoftException in Application.cpp:602: Could not execute script "/home//public_html/wp/index.php"
Caused by SystemException in API_Linux.cpp:444: execve() for program "/usr/bin/php" failed: Permission denied
Premature end of script headers: index.php

user has regular shell (bash) access and is able to login with disabled cagefs. If it gets enabled:
lve_suwrapper: /bin/bash: Permission denied

cagefsctl -e gives:
lve_suwrapper: /bin/bash: Permission denied

ls -la /home/cagefs-skeleton/bin/bash /home/cagefs-skeleton/usr/bin/php

Please advise. Thanks.

Most likely you have noexec set for /home partition, and that is what causing the issue.

Yes, that was it. I missed it.

Thanks Igor.
