I was on 3.5.2 and did upgrade to 3.6. I now get the following message and don't know how to fix it: I can't get any admin access:
Fatal error: Call to a member function add_menu() on a non-object in /home/content/47/10522347/html/wp-content/plugins/wp-native-dashboard/langswitcher.php on line 28
The site (http://kanarvag.org) is running normally.
