Been noticing after, joining a XOOPS sites and then activating the account via the email, it takes you then to a login page, after you login though, it keeps refreshing and doesn’t take you off that page as it should do, due to the activation message remaining in the url....
So instead it tries to activate it again and the error comes up "This user has already been made active"...
Yet then it doesn’t leave that page and just keeps refreshing….this is happening in latest versions of Xoops.

Yes, there is a bug there.
