[quote name=‘mgpshop’]I had similar problems. Try and delete cache folder in /var directory.[/QUOTE]
You should make it a practice after EVERY upgrade, or after major changes have been made for whatever the reason, to clear the entire contents within both the /var/compiled folder as well as the /var/cache folder. All folders and files will be more or less rebuilt immediately as soon as the front & backend of your site is visited. The idea is that this will rebuild the contents of these folders correctly while removing any conflicting trash remaining from prior installs which causes alot of the conflicts/strange behavior we read about here in the forums.
