Google + login not working

Hello! I have a issue.. i managed to make facebook and twitter work.. but now i’m trapped at google+.. i did make a google+ API.. i have the credentials.. but when i go with the default button it opens a new window i select the account i want to login with and then i get this message from my server

domain.exemple 403 Forbidden Error Page

If you arrived here due to a search or clicking on a link click your Browser’s back button to return to the previous page. Thank you.

IP Address: XX.XX.XXX.XXX

and if i go with this url https://www.premier-design.ro/magazin/?SuperSocializerAuth=Google+ it redirects to the site back but it doesn’t authentificate on the website..
