Upgraded from 1.0.15 to v1.1 on a joomla 1.5 site. Admin just wouldn't show properly. So I deleted the whole thing. Then did a fresh install. Again exactly the same problem:
The remaining joomla 1.5 admin works fine.
When I select virtuemart component, the top joomla admin navigation bar disappears, for a very brief moment i can see the virtuemart admin page filled with the product list, then this disappears and I see virtually a blank page with the joomla icons at the top: add atribute,list prices,add products etc. (However there is NO joomla admin navigation bar). (seems to me the admin is in permanent virtuemart 'extended view')
Error: 'document.adminForm.boxchecked' is null or not an object
SO I again removed virtuemart1.1, and then checked the database for any traces... in other words made sure every reference to virtuemart1.1 was deleted, checked all folders too... then did a fresh install and again same problem.
Instaled the older version 1.0.15 and that works fine. So whats wrong with the new version? Any help would be appreciated.
