SMF For Free Support Forum

Hi, I'm trying to make a forum for my friend and after setting up the site, I somehow got signed out but cannot get back in on the admin account for some reason. I keep getting this "Your session timed out while posting. Please go back and try again." error. I tried refreshing over and over again and tried opening a new browser session and nothing is working. Does anyone know how I can fix this? The website is www.trinitychronicles.createaforum.com

Edit: I waited about 30 minutes and still nothing, still getting the same error over and over again and can't get in.

Edit#2: Tried making a second account and it won't even let me register one. Still same error. As always I am clicking the "always stay logged in" box too and still nothing.

Edit#3: Still waiting and still trying again, still nothing. I've never had this problem before... I think the last thing I remember doing on this new forum was trying to edit a board category. Then all of a sudden I got this error.

Make sure you long using this url https://trinitychronicles.createaforum.com/ that's your primary one. don't use www or http only
