Past 1 month I cannot edit or create posts, pages, and products while advanced custom field plugin activated but when I deactivated this plugin, then I can see all posts, pages, and products but I cannot see a list of courses in my course page. I am trapped.
Please help!
This is more than likely caused by a conflict with another plugin or theme.
Have you tried deactivating other plugins to see if that clears the issue?
Are you seeing any PHP or JavaScript errors on the site?
