Hi There,
I have inspected your site and I can see that there is no open graph image tag on the page. Please check the image below.
This could just be a caching issue. Since you have installed a caching plugin LiteSpeed Cache, please clear your plugin cache before testing your site. This can cause the changes to not take place on the front end. It will eventually show up when the cache regenerates, but it’s not ideal if you’re looking to see your changes immediately. Caching plugins are best to turn on only when you’ve finished building the site.
Hope this helps. Kindly let us know.
