Hello,
I do not know if it is due to activing a specific plugin or upgrading my WP website to version 5.6, but every time I try to create (hit "publish") and edit (hit "save" button) custom post types, they end up in the "trash" and when I go to click on "restore", I lose everything and cannot find my custom post type anymore... Same goes for all the posts that were attached to this custom post type.
Can you confirm that Meta Box is compatible with WP 5.6? Would you know how to get back all my lost custom post types & attached posts / images...? I'm very confused about what is causing this issue.
Cordially.
