Topic on Project:Support desk

I was going to make a quick edit, tried to log in and was shown this error. I tried creating an account (I may or may not have tried editing something on westeros.org before) but was told my username was taken, so I said forgot my password, got the email, used the temp password and got the same error.

A google search yields a ton of posts from people "installing" something (seems to be a wiki program to run their own wiki?) and getting this issue, but I'm only trying to log in from my browser. The email does say that my username is associated with my email, so I'm pretty someone didn't randomly take my username randomly, unless the email system is very confusing.

Thank you for any help with this!

I also tried this with chrome, firefox and edge (shudder) with no improvement.

This is likely a configuration issue with the Wiki set-up at westeros.org. This forum, however, is not linked to westeros.org, therefore it will probably be better to make your query at westeros' forum.
