Fix facebook, google and linkedin website logins

Hello everybody, I need a Webdeveloper to fix my websites facebook, google and linkedin registrations / logins. My website is php, accessed via cpanel. Written on Zend framework. Messages received when trying to register using one of the above: Facebook message: Error message1, URL blocked, This redirect failed because the redirect URI is not white-listed in the app's client OAuth settings. Make sure that the client and web OAuth logins are on and add all your app domains as valid OAuth redirect URIs. LinkedIn message: Error message (linkedin), Bummer, something went wrong. Scope "rw_migration" is not authorized for your application G+ (needs to be changed to google) If I click on the G+ (needs to be changed to Google) the first part works I get, Choose an account to continue to [login to view URL] However, upon choosing my google account, it leads to a 404 error message, 404 Application error Opps, You're lost. We can not find the page you're looking for. Take Me Home If someone also knows how to install WeChat login via https so there is no mixed content warnings etc. would also like that installed. Nice extra is google maps api updated, currently does not show on my website. Please note, whilst my website is hosted in the US, I need people in China to be able to access the map. Thank you for taking the time to read through my request.
