I've just installed the upgrade from 5.2.7 to 5.3.8, which DNN reported as a successful installation. However, any pages where the Document Exchange module was displayed now render with a "Critical Error. Object Reference Not Set to an Instance of an Object" error. No modules on the page load. However, I can install the module on a new page from scratch and it runs just fine. Any clues on where to begin looking to see what's going on? DNN logs and windows logs are rather non-informative. 5.2.7 was running just fine... Specs: Windows Server 2008 32bit SQL Server 2005 DNN 6.0.1 Thanks, Tim |
