As you can in this thread - I've had some issues with migrating... So now that I've rebuilt my dev board -- all add-ons, ect working as should... So - I change the boardurl in options to http://jpicforum.info --- Then I decide to move my vB install (which was in the root directory) to directory called OLDvB3 --- Easy enough. Now I move the xenforo install to my main directory. I thought this would be simple enough, with no issues presented. But I see the following error when navigating to http://jpicforum.info Code: Fatal error: Class 'Zend_Registry' not found in /home/******/public_html/library/XenForo/Application.php on line 11 Please tell me how I can fix this issue so that the xenforo install shows correctly. Thanks! J.
