Disabling the stylepress plugin remove the errors that I was getting above but didn’t change the result. I’m now don’t get any debug error messages and just a blank area for the content area.
Not a total new install but a new install of BBPress and we do have wishlist.
Also the page is not totally blank it still has the banner and footer but no menu or content generated. No side bar widgets.
I tried to deactivate the plugin without success.
Changing to the default template did work so its the AIR theme from Yootheme
So what next – look for something in the theme that could be causing it
