I am running DNN 07.04.01 (280). The site has been running for about 12 months without changes and without errors.
This morning when going to edit a page all seemed ok but not i can not see the modules or content in View mode. They only appear in Edit Mode.
Look at http://servicequality.com.au and you will see what I mean. If I log in and edit the page, it comes good until I go back to view mode.
The logs show a "Page Load Exception " for each page loaded and a second error "General Exception " which as the error of "Object not set to the instance of an Object"
Looking for any help or advice you may have.
