Accidently Logged into Mcneel forum with Wrong email, can't log out

Hi there, Google accidentally logged me into this forum with my wrong email account (which it seems to do regularly) But not I can’t in with my other account and there is no way to “switch” accounts.
Any way around this?
I’ve already tried deleting cookies.

Did you try logging out of the “wrong” account (from your profile, behind your avatar) before connecting with the right account?
