New Registration / Login Page throwing 404 – settings seem to be all set

Hello!

My site throws a 404 when I try to register a new user or login. The first page loads: http://girlgeekacademy.com/gd-login/ and I get a new user notification. But I can’t login to add the listing, it just redirects to the homepage.

I have also tried to just go to http://girlgeekacademy.com/add-listing/ and I get the preview but cannot publish the listing.

If I “Allow user to see wp-admin area” in GD settings, when the user tries to login it takes them to the homepage (not the login page). When logged in this way, when I type http://girlgeekacademy.com/add-listing/ I can add a listing successfully.

However I do not want my users to be able to login to my WordPress Admin, I want them to use the http://girlgeekacademy.com/gd-login/ page (which will take them to add a listing successfully).

The gd-login page is there at GD > GD tools and I’ve connected the page at GD > permalinks.
GD pages check says “Login page exists with proper setting”.

I am on WordPress 4.6, and I have a bajillion other plugins… let me know if you’d like me to share them! I have tried deactivating BuddyPress and related plugins (I wasn’t using them anyway).

Any insight you can offer would be amazing!

Thanks!

Sarah
