I cant login to my account in my normal browser/webapp for some reaseon?

I have been having fun on lemmynsfw all day, but as soon as the new update hit I couldnt post and when I logged out of my webapp (firefox) it was impossible to log back in.

Right now I was able to login to a normal Firefox but not my default browser that is Vivaldi.

I get this error in my webapp = SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

And I get this error in Vivaldi = Unexpected token 'O', "Origin is "... is not valid JSON"

Anyone know a fix or what is corsing this?
