Like so many I'm having fatal errors after overwriting my upload/ with the 1.16 core.
System is Ubunutu 18
I do know that php8.0 is required, system is manual mode 8.0.20. I've verified apache module config with a phpinfo() page.
Logged errors are:
PHP Fatal error: Uncaught Error: Non-static method Misc::currentURL() cannot be called statically in... some php core file in upload/
Where should I look next?
