og:Image Not Working – Tried Everything, I Think

When I post my website URL into Facebook it shows the wrong og Image.

I have the Yoast plugin installed.

I have the Yoast SEO section filled in correctly – including the Front Page Settings and Default Settings area.

This should be the image that shows as the og image: https://www.themsgym.com/wp-content/uploads/2018/04/sq.jpg

Instead it seems to be pulling the image from my last post (which is not even shown on my home page).

I have run the Health Check plugin with no issues.

I have deactivated all other plugins and even the theme. I still get the same error.

I’ve run the Facebook Debugger tool many times and clicked the Scrape button many times.

When I look at my source code I can see the og image is wrong… but I can think of no other place to enter the correct og image URL other than Yoast Social areas I mentioned above.

My home page is made of widgets but the Settings – Reading section is set to show latest posts vs show a static page, if that makes a difference.

Any help?
