Recently I upgraded from PHP 5.2 to PHP 7.2 and I got a a HTTP ERROR 500 when I try to visit the phpBB forum. I restarted Apache and it fixed the problem but the forum wasn't stable. I was still on phpbb 3.2
After that I could log in to the forum but I got the HTTP ERROR 500 when trying to go to the control panel, eventually I just managed to get to the control panel without doing anything but when I tried to do a few things with the database (reset dotted lines, etc. ... cant remember all of them) I got a HTTP ERROR 500 and couldn't get back to the board since.
I tried upgrading to the latest version of phpBB by following the upgrade instructions but there are some files I could not delete via FTP. I copied the files over anyway but two files couldn't be copied over -
I tried restarting Apache but still getting a black screen https://forum.clogherhistory.ie/
I tried looking for the error log but only have found php_errors.log
which is a massive file but hasn't had an entry for over 10 days. I don't have access to the control panel to view errors.log
