I was helped with putting blog into maintance mode….
Have the same issue. And in console get this:
Failed to load resource: the server responded with a status of 500 (Internal Server Error) http://xxxxxxxx.com/wp-admin/admin-ajax.php
Have the same problem but only on edit post page. When I check some category it needs to load big meta-box with custom-fields. But I get blunk area instead of this block. Screen applied.
