suPHP requires specific permissions and ownership for scripts to run:
- all folders within public_html – user:user 755
- all files in public_html – user:user 644
- public_html itself – user:nobody 750
(“user” refers to account name)
Without these permissions set you will see a lot of errors such as: “403 Forbidden”, “500 Internal Server Error” or other messages.
In example, CPanel error logs may show something like:
SoftException in Application.cpp:631: Directory “/home/[your-account]/public_html” is writeable by group
