Timeout & Open Graph

Hello!

Long prehistory.

1) On three pages of the my site, including, on the home page, Open Graph does not work properly:

https://hbd.su/page/partner/main

https://hbd.su

Errors were as in this screenshot:

2) I’ve been looking for a solution for several days, I’m tired and a little desperate. Today in the support of my template I was given a link with a similar problem. It stated that the solution is to cache and mention your plugin.

3) I installed it and set the recommended settings.
The problem was solved for the home page! ))
But for the other two, everything remains as before ((

I ask to help find a way out of this situation. I have a feeling that with the help of additional settings of your plugin you can completely solve this problem on my website.
