Hello, All.

I've installed the latest version of OP on a CentOS 7 box via RPM.  Installation seemed to go fine; I received no errors.  Yet, despite everything I've tried, I can't get to the login page.  Instead, I get a 403 error - Forbidden You don't have permission to access / on this server.

Here's output from https error_log:

There are lots of "not found or unable to stat".  A search of the system doesn't find any php or index files.

Your help in resolving this would be greatly appreciated.
