When the settings pages first load the page looks normal for a moment but then:
On GP Hooks page the right column with the “Save Hooks” button disappears.
On the Main settings page, everything disappears except for “Customize” Button and the made by footer line.
Additional Information: I found that the conflict is with WPTimeCapsule Plugin. Once it is deactivated the missing settings sections reappear. I have contacted their team about this.
Let me know what they say – I don’t think GP is doing anything special when it comes to creating those pages, but I’m definitely interested in finding out what the incompatibility is.
