Problem installing Facebook connect

I am having trouble making this. I have read the help topic on this and suspect the problem is with the Site URL and APP domain. They need to be entered in fields visible here...



I get an error that says the APP domain "must match" the Site URL. I think the problem is that our forum's URL does not include the word "forumotion." How do we resolve that?

Also, must the Site URL be https://help.forumotion.com/ ?

Thanks.

Put the original link.

Thanks. What is the original link and where should I put it? Do you mean my forum's URL?

The link before you purchased a domain name.

We didn't purchase one. We still have the original. It's of the form: *****.super-forum.net.

You need to contact Facebook if you are having trouble filling out the information.
