Hmpf, it seems that on MacOs it is possible to use OAuth as oposed to
BotPasswords on Windows? In any case, the working is similar. I am not a
huggle dev but an user. First that comes to my mind is that you did not
authorize huggle to use rollback on enwiki. If you're using
OAuth/BotPasswords be sure to select too a group of permissions that allows
the application to use rollback. If you already have done that, be also
sure that you've Special:Mypage/huggle.css and Special:Mypage/huggle3.css
configured correctly (enable:true). If nothing helps, hopefully a more
experienced user will reply or you can create a ticket in the Huggle
project of the
phabricator.wikimedia.org issue tracker. I hope that your
issue gets resolved soon.
Best regards,
