I have setup Limesurvey before but never on a RHEL server before. I have gone through the steps and confirmed that the web server itself is working and has php 7 (see phpinfo below).

When going to the admin page for the installation, I receive the following error:

Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0

Fatal error: Unknown: Failed opening required '/var/www/html/limesurvey/admin/admin.php' (include_path='.:/var/www/html/php') in Unknown on line 0

I have tried several paths for /var/www/html/php and various permissions.

Any idea what I'm missing?

Thank you! I didn't even consider that but it was a huge help!
