 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 didnot help.
 Then I installed 2023, activated it but the error was still there. The
 MiniMeta-Widget is active and seems to be the course of the error.
 Unfortunate (?) I am not a programmer there I will not deal with MiniMeta.
