Looks like your site is too slow — the Facebook crawler can’t get the information it needs from your page.

You might want to look at the following article I wrote about WordPress performance https://surniaulula.com/2012/12/01/wordpress-caching-and-plugins-for-performance/ or google “wordpress performance” for similar articles.

If you’re on shared hosting, be careful of any plugin that creates files, since disk I/O is often a bottleneck on shared hosting.

About 75% of plugins and themes are badly written — try running the P3 plugin to see of you have any really badly performing ones that you could disable or change (for a faster alternative).

I just tried the P3 plugin and it said the plugins represent 3.1% of the load time. That’s pretty low isn’t it?

I am on a shared server because I really don’t require anything else since my traffic is so low. Could this be the server side?

Thank you for replying.

Oh wow, I checked the theme and that like 90% of the load time. I changed it to another theme and bingo, everything is back.

Only one problem, and not sure if your plugin will help or not. I used to be able to select the image I want (from the post) when sharing to Facebook, but I still can’t do that. It arbitrarily picked one image. Now I didn’t try sharing until after I did the debugger so I don’t know if that had an impact. So I checked another post link and when trying to share to Facebook, it was all wrong again so I do need to run the debugger still for each post before sharing. But any idea on how Facebook can grab all the photos?

Thanks a MILLION for your help on this!!

If Facebook has crawled a URL *once*, then whatever was there is what it will use (even if it has been updated).

Also, here are some P3 benchmarks to give you an idea of performance targets:
