Fedora release 31 (Thirty One)
PHP 7.3.17
Wordpress 5.5
I have two sites running on my server, both WP version 5.5 and both have Version 1.0.1 of the Multilevel Navigation Menu. One works fine and in the other I am getting these message on every page (as far as I can see):
Deprecated: Non-static method Multilevel_Navigation_Menu_WP::mnmwp_register_menu() should not be called statically in /data/home/linux-tu/public_html/wp-includes/class-wp-hook.php on line 287

When I deactivate the plugin, the messages do not appear.
