Hello @aldoctorcenter,
As per Facebook login security All new apps created as of March 2018 have this(Enforce HTTPS) setting on by default So you should plan to migrate your site to https.
If you have any old Facebook app,which allow to set the Enforce HTTPS to No ,set it to no and try again.
or add or uncomment
if(is_ssl()===false)
$redirecturl=preg_replace(“/^http:/i”, “https:”, $redirecturl);
after the 5th line in authorization.php file, and when the facebook app redirect the site with https url of your site,remove the s from https and reload the url without modifying the other parameters in the url.(not recommended solution)
For new apps Enforce HTTPS is set to No and also no way to change it. Your only option is to migrate your site to https.
(Chrome has recently announced that they will mark all HTTP sites as insecure soon, from version 68 on, that will be released in July 2018. So you’re gonna have to go HTTPS rather sooner than later anyway.)
LetsEncrypt is a free, automated, and open Certificate Authority that enable HTTPS on your website.
However there are certain deprecations and changes in Facebook,which require app review for the app to work with the existing plugin code, so we are working on it.
Hope it helps.
Thank you
