 With php7.4 all was smooth, with php8.0 there is this nasty error:

 `call_user_func_array(): Argument #1 ($callback) must be a valid callback,
 non-static method WP_Widget_MiniMeta::register() cannot be called
 statically`

 I inactivated any plugin and I removed any themes but 2014 it did not
 help. Then I installed 2023, activated it but the error was still there.
 The MiniMeta-Widget is active and seems to be the source of the error.
 Unfortunate (?) I am not a programmer there I will not deal with MiniMeta.

 Hi and welcome to WordPress Core Trac!

 Yes, the [https://wordpress.org/plugins/minimeta-widget/ MiniMeta Widget
 plugin] should be the source of that error. Someone else
 [https://wordpress.org/support/topic/after-upgrade-to-fedora35-and-php-8/
 reported the same error].

 Since the plugin has not been in active development for years, I can only
 recommend trying to find another plugin that would do what you need. If
 you want help with the search, you could open a topic on the WordPress.org
 support forums:
 - [https://wordpress.org/support/plugin/minimeta-widget/ Forum for
 MiniMeta Widget], where I did not find any topics (yet) about an
 alternative
 - [https://wordpress.org/support/forum/how-to-and-troubleshooting/ Fixing
 WordPress forum]
