I got WP Maintenance Mode (v.2.0.2) to work once I removed the WP Super Cache plugin. However the Circle Flip Maintenance Page changes do not seem to take into effect. I was able to “update” Circle Flip Theme to 1.5 today. And still no luck with the CF Maintenance Page “overrides” (figure this theme setting is intended to override the WP Maintenance Mode plugin settings).
So the good news is that the Maintenance Page is working.
I am encountering a few other strange issues/bugs, but I will post them in a different thread.
