Given URL is not allowed by the Application configuration:

Hi,

I just encountered a wierd circumstance I'm not sure why this is happening. I had setup a standard authentication login process for facebook. Worked great. no issues at all. works as expected.

Then I had a user test it. They got this message:

Given URL is not allowed by the Application configuration: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.

This user entered the website with the www. in front of the domain. If they remove the www. the login works fine.

I went into my setting on my app and added www. to all the domain entries. Still doesnt work. I have tried every different combination I can think of, it just will not work when the www. is used on the front of the domain.

Any ideas, have we seen this before? I did a search on the forum foe this, found one thread, but it was inconclusive.

Any help in the right direction would be greatly appreciated. I can provide admin logins as needed.

Thanks

Thanks,

After looking closely at the Setup guide, my issue (in case others have the same) was the Valid OAuth redirect URIs. I added the appropriate URLs in that field (with and without the www. ) and it fixed the issue.

Thanks for your guideance
