Hello,   I have recently moved three of my Joomla sites from Namesco to Krystal.   Initially all was fine and I made the move using an Akeeba backup.   Then a couple of days later overnight all three sites stopped working  and initially showed

This page isn’t working
www.holytrinitywestlulworth.org.uk is currently unable to handle this request.
HTTP ERROR 500

but now

Fatal error: Failed opening required '/home/efdfedee/holytrinitywestlulworth.org.uk/index.php' (include_path='.:/opt/alt/php83/usr/share/pear:/opt/alt/php83/usr/share/php:/usr/share/pear:/usr/share/php') in Unknown on line 0

 I am contact with Krystal support who are looking into the problem and their response is below

Thank you for your response and details.

We have looked into the "Failed opening required" error on your sites. I've confirmed that the files exist, and that their ownership and permissions are correct. We have also ruled out some other settings as the cause, but I can't see immediately why PHP cannot open the files.

I've gone ahead and escalated the ticket to our Tier 2 team, so our senior engineers can look into this for you.

 

For Akeeba I was just wondering whether Admin Tools might possibly be blocking something or perhaps you might have seen something like this before..   I have tried renaming the   htaccess file but it makes no difference.

Thanks    Dennis

I can tell you that this is definitely not related to Admin Tools. Admin Tools runs inside Joomla. Your problem is that PHP on your server is not able to open Joomla's index.php file at all. This looks like a server configuration issue. Without having the exact configuration of the server at my disposal I cannot diagnose it further than that. I trust that your host's level 2 support will be able to diagnose and fit is just fine.

PS: Last time it happened to me on a server under my control I had simply forgotten to set up the correct user in the PHP-FPM pool. I left the default www-data:www-data which had no read rights on my web root and files. I fixed it, restarted my web server and PHP-FPM services, and the problem was solved. Which is to say, if the person troubleshooting it knows how the server is meant to be configured it's very easy to identify and fix the root cause. Someone from the outside would be "um, yeah, something's wrong, alright".
