Fatal error: Call to a member function add_rewrite_tag() on a non-object in .../wp-includes/taxonomy.php on line 333
When I install the plugin I get this error. It does not allow me to access the admin at all.I have tried deactivating all of my installed plugins and I still get the error. I have not taken the step to install from a vanilla install and add plugins one by one.
Any help would be greatly appreciated.
Some plugins I am using include Members by wpmu, Gravity Forms
