Summary of the issue you are facing:
I am seeing the following errors in the administration dashboard:
There are some errors regarding your setup.
The PHP memory limit is below the recommended value of 512 MB.
The PHP OPcache module is not properly configured. The OPcache interned strings buffer is nearly full. To assure that repeating strings can be effectively cached, it is recommended to apply "opcache.interned_strings_buffer" to your PHP configuration with a value higher than "8".. For more details see the documentation ↗.
This instance is missing some recommended PHP modules. For improved performance and better compatibility it is highly recommended to install them: - intl increases language translation performance and fixes sorting of non-ASCII characters For more details see the documentation ↗.
Steps to replicate it (hint: details matter!):
Unsure - I log in using an administration account, and go to administration.

The messages here are from when I restarted apache2 to ensure there wasn’t something amiss there. One of those was following a change to the .htaccess file to add the php memory limit there - which had no effect. I also opened for editing, checked, and saved the php.ini files (no changes - they were already set to the values provided further down in this message), and reloaded apache (systemctl restart apache2)
The other log with a current timestamp was the other_vhosts_access.log, which does not include anything other than the accesses from clients (I did look, but none of the timestamps matched).

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

With the two errors I received, I went looking at the configuration indicated. There are 3 possible php.ini files, one in each of 3 directories under /etc/php/8.3:
apache2 → php.ini
cli → php.ini
fpm → php.ini
Looking at all three, the values indicated as not being set are, indeed, set:
root@wmssfs00:/etc/php/8.3/apache2# grep memory_limit php.ini
memory_limit = 512M
root@wmssfs00:/etc/php/8.3/apache2# grep opcache.interned_strings_buffer php.ini
opcache.interned_strings_buffer=16
root@wmssfs00:/etc/php/8.3/apache2# cd ../cli
root@wmssfs00:/etc/php/8.3/cli# grep memory_limit php.ini
memory_limit = 512M
root@wmssfs00:/etc/php/8.3/cli# grep opcache.interned_strings_buffer php.ini
opcache.interned_strings_buffer=16
root@wmssfs00:/etc/php/8.3/cli# cd ../fpm
root@wmssfs00:/etc/php/8.3/fpm# grep memory_limit php.ini
memory_limit = 512M
root@wmssfs00:/etc/php/8.3/fpm# grep opcache.interned_strings_buffer php.ini
opcache.interned_strings_buffer=16
root@wmssfs00:/etc/php/8.3/fpm#
Is there someplace else that these configuration settings are made? Something that would override these php.ini files?
Thanks in advance for any and all assistance.
