I have had no issues on a site and then today when i went to the clients site i noticed that I was not able to log in through the front end of the forum i set up.

Also, even though I have it set up correctly to allow guests to see and go through the forums when i visit the site on another browser I see nothing and then when I click on sign in I get this " sign-in/?redirect_to=https%3A%2F%2Fvitalwords.org%2Fcommunity%2F"

it does not send me to a sign in page and the same goes for the sign-up link. The "Forums" tab on the menu only has the single promotion line i set up and nothing else. 

I updated everything. Have had people, and myself sign up and sign in through the Forum before. 

I can log in through the backend and I have no problems, everything is visible and looks normal. 

I have tried to create a new page to direct the sign-in to. I have tried doing a redirect back to the wpforo and to my new page. 

I have purged hosts, wp, wpforo and flushed permalinks Many, many times. 

boards slug looks fine. 

Tried repair functions as well as disabled all other plugins but wpforo. 

Used updraft to restore to a few days ago with nothing, so maybe it has been longer that I thought. 

I have not changed any settings before this event occured.
