Robert,
Glad you're liking JFBConnect! As for your issue, yes, it can be random, but there's also a few times that it can happen that can be fixed. Can you try the following:
* Run the page you're having issues with through Facebook's URL Debug Tool:
developers.facebook.com/tools/debug
* Check that the URL shown there is what you'd expect and that there's no redirects shown
* Click the "Send" button again and make sure the link shown in the popup seems correct (you may not be able to see it all)
* Try Sending again (Sometimes just running the page through the Debug Tool will clean things up).
If that doesn't work, we may need to look into it more, if you want. If so, let us know what URL you're having issues with and we can investigate. If you don't want it public, you can Private Message it to us using the arrow under my picture (<
) and hitting the mail icon.
Thanks,
Alex
