Invalid parameter when adding JS image

What site are you having issues with? I just tried to authenticate with Facebook on www.ehcanadatravel.com/ and had no issues using Facebook. Can you describe exactly what steps you are taking, on what site, and the error you're getting. For the error message, please let us know if it's in the login popup window or on a separate page, etc.

Any details you can provide will greatly help us narrow things down.

Thanks,
Alex

Colin,
It seems like you're talking about multiple different issues you're trying to resolve. Please let me know if I'm mistaken:

The errors are in the backend of JFb under channels. It seems to work fine from the front end.

This is where you get the app_secret_proof error message? Can you send us a picture of the error message you are getting so we can understand exactly where you are seeing it?
Again, if you're trying to add this to JomSocial, I'd ask in their support area. I don't know their template system like they obviously would. If you're having issues adding any output to their template files, they should be able to help you very quickly.

Thanks,
Alex
