How to allow apache to read files created by other users?

Question

Apache HTTP Server

I have a CPANEL/WHM project where another application creates files under a different user.
And when I follow the direct link to these files, apache returns 404.
Apache log:

Caught race condition abuser. attacker: 502, victim: 0 open file owner: 0, open file:

This means that apache does not have access to files created by another user.
How to fix this? Have access to whm

Found the answer here
It was a patch for apache in WHM. Apache rebuilt, reconfigured everything, everything is ok. There was just some patch that forbids apache to read files not created by it.

Answer 2

You need to add the user to the www-data group (to the Apache group)
