This is expected behavior. After installing and activating a plugin, you are supposed to Rebuild & Restart. There's a special button in the ACP to perform this.
Then there is no problem. Thank you for your answers.
When I try to install Google, Facebook and Twitter SSO plugins, and try to activate and restart the forum ...they are not working ...I mean they are not showing up in the social authentication.
How to fix this issue?
This happened when the forum is updated to the latest version.
I'm having the same issue... any updates on this?
This forum is running all three of those I think, without any issues as far as I can see. It's on the latest version.
you must forgot to set related informations in admin panel(social authentication)
