I am searching in the primary site admin area. We are using Multisite and have iThemes Security Pro enabled at the network level. We are running on NGINX and so far everything works flawlessly except for when I switch to the primary site dashboard, then click on Posts / Pages in the sidebar still in the admin area, when I do a search there above the full list of pages / posts it returns the custom 404 slug created in the “Enable hide login area”. Immediately turning off this feature fixes the admin area search front end searching works fine but back end admin facing searching returns a 404 not_found slug.
Great, thanks so much! But can you agree with me that some sort of email –> username lookup system would make it easier to attain this information?
