It is your plugin that is causing the error
Jetpack has absolutely no control over the look of your posts on Facebook. Since you use the WordPress SEO plugin to manage Open Graph Meta tags on your site, the problem is either with WP SEO, your site, or Facebook itself.
As I mentioned earlier, WP SEO’s meta tags are displayed properly. We can rule that plugin out, it’s not causing any issues, it does its job just fine.
We’re left with your site, and Facebook:
- Either your site fails to load when Facebook’s bot first crawls your site.
- Either Facebook’s bot is broken cannot grab your Meta tags.
Since Facebook can grab the tags just fine when you hit the “Fetch new scrape information” button in Facebook’s debugger, I think we can rule out Facebook as well.
We’re left with one possible conclusion: your site fails to load when Facebook’s bot first crawls your site.
You’ll consequently need to find what slows your site down, or how to speed up loading time on first page load. There are any ways to approach the problem:
- You could try to deactivate plugins, one a time, until you find what causes problems on first page load.
- You could try to use caching services like CloudFlare and see if it helps.
- You could try making tests on a different server, or with a different host, and see if it helps.
I hope this helps.
