Trying to set up a new site and connecting to a github repo as per usual. It’s asking me to login to github via a popup window. When I login with correct credentials I get an error message - ‘your browser did something unexpected’ and no other error message.
Haven’t seen this before. It doesn’t even seem to get to validating my input as if I also put deliberately incorrect credentials I get same page but no error message about password not matching.
