The first time I attempted to go to your page, I received the following fatal error at
www.haitiancorner.com/en/Fatal error: Internal Zend error - Missing class information for in /home/clients/robert/domains/haitiancorner.com/html/components/com_invitex/helper.php on line 20
I then attempted to do the error check on your page and received the error you are seeing. But when I visited the above link again, the page loaded and the error check gave me the following:
Test: Facebook Javascript library inclusion
Fail: Another Facebook extension is installed, including the Facebook Javascript library, and may conflict.
Please see our Common Support Questions "What do these Autotune Error Check errors mean?" at
www.sourcecoast.com/jfbconnect/docs/common-support-questions/ for how to resolve this.
Another loading of the page brought me a blank page (likely another PHP fatal error). So once you fix the intermittent PHP errors on your page, please follow the suggestions above to fix the FB javascript library issue.
