Error Code: 200 OK on every resource select. [SOLVED]

Check that you have all of the required permissions to view the current manager page. Sometimes you can get this if for example a template dropdown can't populate because you don't have sufficient privileges.

I always start with a policy template that works and start testing subtracting privileges or adding until I get the desired permissions.

Working sollution:

I had the same problem - upgrade from 2.2.7 to 2.5.7 (through FTP) and error 200 almost everywhere in manager.
Deleted cache, flushed session, cleared browser cache - nothing helped for me.

I deleted manager and connectors folder, then uploaded it again, and did setup again. Thats worked for me.

Same problem, my solution I needed the 5 above AND view_template ticked.

Ah... perfect... checking view_template did it for me... many thanks.
