Yup, just ignore if everything works. That's purely a check on our end to see if things seem good, and all we do is look at the reported Site and Base URLs that are reported by Facebook. It's not perfect, but helps call out user configuration errors. Occasionally though, those fields come up blank, and it's usually something that clears itself up after a few minutes/hours.
If it persists, try enabling API Error Reporting on the Front-end (in the FB API configuration) and log in again (on the front-end). Make sure that no errors are reported there. Also, you can always check your Facebook application to make sure the Site URL and Base Domain are still correct, in your case, they should be:
site url:
www.kiddies-world.com/
base domain: kiddies-world.com
In general though, I think your good. Let us know if you run into any troubles though.
possible misconfiguration
