Facebook Login Redirect Broken after Joomla 3.8.4 update

We're planning to get the updated release out today pending no unexpected issues arise.

Thanks,

Thanks for posting that link. It's definitely true that Joomla 3.8.4 introduced the e issue. We have a new release coming out today that is much more robust to future changes like made in Joomla 3.8.4 and, since we dug into things deeper, we fixed a few other language URL issues that we hadn't been able to fix in the past. So, our new release is still recommended, but upgrading to 3.8.5 should also get you going if you're experiencing the login issue.

Thanks for your patience and reports on the issues everyone, they really helped us narrow things down quickly!

That's awesome news. Thanks for letting us know things are back to working well!
