Disabled Functions :: allow_url_fopen
The PHP native function allow_url-fopen should be enabled. Contrary to what some hosts claim, it is not a security risk. They confuse it with allow_url_include that is a security risk and that is why this PHP function was deprecated in PHP 7.4 and subsequently removed. Ask your host to enable allow_url_fopen or you may be able to do the from the cPanel or a similar page provided by your host.

If there are caching errors, you could disable caching for a while and check if that improves the behaviour of the site.

When the field Error Reporting in the Global Configuration is set to 'SImple', many warnings and possible errors are filtered. Change it to 'Maximum' and turn on also the option 'Debug System'. Copy and paste the error messages and PHP call stacks here for advice.

BTW, if the option 'Log Almost Everything' is selected in the Logging tab, PHP will write the messages into the log file administrator/logs/everything.php.

I've wondered if removing old jos_ database tables could help
The prefix jos_ was the only option in the distant Joomla past. Does the website now have a different, random string of letters as its database prefix? Make sure you do not drop active, live production database tables!
