Can’t access my user page

Hello! When I go to the forums and click on my own name from a comment or whatever, instead of going to my forum profile page, I get an error page saying “It doesn’t appear that this user exists.” As a result, I can’t get to my profile page to see the listings of my forum posts, activity, etc. I don’t know if it has anything to do with the fact that the link for my supposed user page has spaces between the words of my username, instead of dashes, underscores, etc.

Any help in fixing this would be appreciated!
