Hey Scott, folks!
Looking to use AdM, since it allows for manual placement of ad blocks in posts.
I'm looking at one issue: the Ads>Edit page is blank. I can create news ads, and the settings page looks fine.
I've tried disabling all other plugins, no go.
Using 3.3.8 on 2.7.1.
Let me know if there's some things you'd like to test out to better troubleshoot.
