Hi,
I am using 4.7 pro version of user role editor, php 5.4.20, wordpress 3.7.1 multisite
when i am going to activate licence key from the network, settings, user role editor menu its giving Fatal error: Call to a member function remove_cap() on a non-object in /wp-content/plugins/user-role-editor-pro/includes/pro/class-user-role-editor-pro.php on line 173
Please let me know if role “Administrator” with id=”administrator” exists at the main blog of your network. You should see it as “Administrator (administrator)” at the URE drop down menu.
