Facebook Login Problems

mikeymccoy

Every few days when I or someone else tries logging into my Vanilla forum this code appears:

{
"error": {
"message": "Invalid redirect_uri: Given URL is not allowed by the Application configuration.",
"type": "OAuthException",
"code": 191
}
}

I go back into authentication > facebook and then notice the in the box where it says "When you create the Facebook application, you can choose what to enter in most fields, but make sure you enter the following value in the "Site Url" field:"

I noticed that that keeps changing my website address from the "http://" to "http://www"

each time I have to back "http://www.facebook.com/developers/apps.php"

and under "Website" change the "Site URL" so that it matches the one inside Vanilla. But then a day or two later I get that same error message only to and find Vanilla has changed back to to either http:// or http://www which requires me to change it again.

Any ideas how to solve this so I don't have to keep going round in circles.

Hi,

Please add add your domain without using "www" in "Basic Info --> App Domains", like "example.com".
This will resolve the issue.

Thanks,
