error 403 when sharing on facebook

Hi, Support team

I don’t know how to fix this. When I try to use facebook button on the bottom of the page and try to share the article it shows error 403. It appears on my new post ,every new post. The old post works fine.
Do you have any idea how to fix this?

Best regards,
Lip

Try the Facebook debug tool on one of your new posts.

Might be a problem with Facebook, or you might have conflicting OG tag data, which you can see by looking at your page source.

Thanks a lot. Chris S
I try using Facebook debug tool and it shows on the picture.
I’m very new to website and I’m not sure where to fix OG tag data.

I use Yoast WordPress SEO to put in all the OG tags for Twitter and Facebook.

But try the Yoast SEO plugin first (or any of the other “OG Tag” plugins on wordpress.org), which will insert all of that stuff into the meta data for the posts.

The OG (“Open Graph”) tags basically have a custom title tag, description tag, and image link tag, and canonical URL, for Facebook to “grab” from your site.

You mean this section right?
If yes I already try this but it still shows error 403.
More information. This problem happened after I change my hosting.My older posts work fine.They can share with no error 403.But now I try to add new post and the problem appears.
I’m not sure if it’s about the .htaccess file or something?
