After update the mB settings page, my site get a fatal error.
I only did an update.
Fatal error: Declaration of MBSP\MetaBox::is_edit_screen($screen = NULL) must be compatible with RW_Meta_Box::is_edit_screen($screen = NULL): bool in .../wp-content/plugins/mb-settings-page/src/MetaBox.php on line 68
My site works fine without the plugin. How to correct this problem? How to find an old version of the plugin?
