I am getting the following error from that link in the Facebook Sharing Debugger:
The parser's result for this metadata did not match the input metadata. Likely, this was caused by the data being ordered in an unexpected way, multiple values being given for a property only expecting a single value, or property values for a given property being mismatched. Here are the input properties that were not seen in the parsed result: 'og:site_name, fb:app_id, og:locale:locale'
Could you please turn off your compression from JCHOptimize and then re-scrape the page with the
FB debugger
. If the error is gone, then please try to share again and see if the preview is correct.
