I am having the same issue. Jet Pack works great on my business site, but will not certify on my personal website. This is the message that I get
nvalid request, please go back and try again.
Error Code: invalid_request
Error Message: Mismatch in redirect_uri.
Yeah, I only put an email address in that field…no links. Not the problem.
Should I delete the plug in and reload it? I would hate to have to use something else because I like the layout of this one, but I have spent way to much time trying to fix this issue.
