How to resolve "Using both mod_userdir and mod_ruid2 is not a supported configuration."

Question

When enabling mod_userdir protection in WHM (WHM >> Security Center >> Apache mod_userdir Tweak), you may run into the following error.

Detected mod_ruid2 in use.
Using both mod_userdir and mod_ruid2 is not a supported configuration.
Changes were not saved.

How can this be resolved?

Answer

mod_ruid2 with mod_userdir is not a supported configuration as suggested by this error notification.  You will want to disable mod_ruid2 and enable mod_suexec in its place.

1) Navigate to EasyApache 4 in WHM.

2) Customize your current profile.

3) Navigate to "Apache Modules" and tick "mod_ruid2" off.

4) Search for mod_suexec and enable it.

5) Select "Review" on the left-hand side and provision the new Apache build.
