I get this every time I click on the Go To Login button when I try to go to the chat, I have never logged on before so not sure why I’m having the issue.
Welcome here!
But, I must admit; I haven’t seen anyone get that error before.
Are you trying to login using a Google account? Are you accessing it using an ordinary web-browser, going to: https://wolfery.com ?
It could possibly be some cookie is acting up.
Try clear all the cookies for mucklet.com and wolfery.com, and try again. Or alternatively, try with another browser. Same issue?
