Wow, you are great, incredible! Thanks!
Thank you, yes I digged deeper. ABSPATH warning although remains, but sending e-mail problem was not related (it was just a coincidence). Yes, it seems that even some very popular themes and plugins are not ready for 8.0.
However, uploading theme error: I have no idea why it doesn’t work, it really seems to be a WordPress problem, because it happens also a totally new install (and only at PHP 8.0) But I can do it manually.
PHP Fatal error: Uncaught ValueError: Unknown format specifier """ in /web/***/**/blog/wp-admin/theme-install.php:63
Stack trace:
