I just upgraded from 36.6. to 3.6.7. and since then, I cannot open any pages on my front end menu. The screen just flickers, then goes back to the home page, although the browser reports that is is showing the page I'd tried to open.
Plus, if I try and open or edit any posts or pages, I receive the following message:
Fatal error: Call to a member function get() on a non-object in /my website address/wp-content/plugins/amr-users/includes/ameta-admin.php on line 36
Disabling AMR Users removes these problems. Any help/advice appreciated.
