A few errors with WP 5.7 RC2 multisite and PHP 8

Hey! Thanks for a nice plugin. Comes in handy for a quick fix.

I’ve tested it on two different sites running WP 5.6 and PHP 7.4, smooth sailing.

But on my WordPress 5.7 RC2 test bench running PHP 8.0.0, the following errors are thrown:

Warning: The magic method WP_Htaccess_Editor::__sleep() must have public visibility in /home/oldrupdk/oldrup.net/wp-content/plugins/wp-htaccess-editor/wp-htaccess-editor.php on line 935

Warning: The magic method WP_Htaccess_Editor::__wakeup() must have public visibility in /home/oldrupdk/oldrup.net/wp-content/plugins/wp-htaccess-editor/wp-htaccess-editor.php on line 945

I’m not sure whether those relate to WP 5.7 or PHP 8, but something is not quite right.

Are you able to reproduce?

Kind regards
