When you set your Facebook sharing details inside of OptimizePress sometimes those details do not show up on Facebook itself. That is because Facebook has a cached copy of your page and its details and that cache needs to be refreshed.
You can do that by going to this page and entering your page\’s URL:
https://developers.facebook.com/tools/debug
Click the debug button to request Facebook to display the meta information of your page. Then, hit the Scrape Again button to display the latest meta.
Once you do that, Facebook will recache your page and things should be fine after that.
