FIX FACEBOOK LOGIN FEATURE

The site uses an altered platform of the phpSound program. The site is [login to view URL] The Facebook login feature has stopped working. We get the infamous "URL Blocked: This redirect failed because the redirect URI is not whitelisted in the app’s Client OAuth Settings. Make sure Client and Web OAuth Login are on and add all your app domains as Valid OAuth Redirect URIs." error when trying to log in via Facebook. Our Facebook app settings should be correct so there may be some need of updating the program to fix the error. We have the most recent update of the program if needed for script updates. As stated there have been a lot of alterations made to the original script but none that should have affected the login feature as it was working fine up to about three weeks ago. We need someone who can figure out the updates needed or figure out what we have done wrong with our Facebook app settings. We would like this to be a quick fix project to find a programmer to work with on this site as further updates and projects are coming very soon for this site. We are looking to blend some aspects of phpSound with phpSocial in the future. Both programs are from the same company using the same platform so it should be a fun project! But for now, we just need the Facebook login fixed. Please refer to me as Mr. Danny when replying about this project. Thank You
