Hello
Thanks for getting in touch with us.
I checked your URL with facebook debugger and it shows Curl error: 61(BAD_CONTENT ENCODING)
The issue you are facing is pretty common with W3 Total Cache users. If you have this and the Gzip compression option enabled, please disabled it from W3 Total Cache Perfomance > Browser Cache.
After that, just clear the cache and that should fix the issue
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
