This is most common when the domain on the live URL has not been added to the domains whitelist inside of CFProTools.
The add-ons are designed to function properly in the preview screen, but on the live URL where actual traffic will go to see the page, you will need the live URL listed in the DOMAINS tab in CFProTools.
If you are still having trouble after adding your domain, please let us know and we will do our best to help.
You may need to wait up to 5 minutes AFTER adding your domain to allow time for the cache to clear and for the changes to propagate.
