If you are finding it difficult to sign-in or login to your site with social media account, below is the solution on a CMS platform (Content Management System).
I recently resolved this issue on a website i manage with this simple steps:
For facebook: sign-in to your facebook developers platform and Create your Account if you’ve not: https://developers.facebook.com/
— under facebook login — go to Settings — Valid OAuth Redirect URIs — (after filling your app domain details, Copy and Paste the code below Ctrl&Shift V) “replace the example.com with the domain name you’re activating social login for” https://example.com/?SuperSocializerAuth=Facebook
LOGIN to https://console.developers.google.com/ and Create your google Account if you’ve not, afterwards:
CREATE your linkedin Developers Account: https://www.linkedin.com/developer/
https://EnterYourSiteNameHere.com in “Authorized Redirect URLs” option in your Linkedin app settings for Linkedin login to work.
It should work fine!, just say thanks to my mail: firstname.lastname@example.org
