If you are trying to login to your connected platforms, but after login you see the vBulletin message:
Please, don't panic! It is NOT A BUG!
It is a common message when HTTPS is used.
If you're seeing an "Invalid redirect" error message then you might be able to fix it by adding the domain to the vBulletin white list or "Redirect Domain Whitelist" (find it here: vBulletin Admin CP>vB Options>Site Name / URL / Contact Details>Redirect Domain Whitelist).
It's to allow the vB code to redirect users from your site to other domains and resolve redirect issue.
