The CPT and and taxonomies are not working as they should after WP 5.7 update.
I installed a fresh WP and installed & activated both MetaBox with MB Core plugins and my license key is active.
I can't see or edit the custom post types and or their functionalities. What I basically see a blank page. This has also happened in my previously built sites. Functions seems to be up and running on the backend however editing them through panel is problematic.
Counting on your prompt response.
