In the end, u could not fix it and I deleted and add the post again. Still not understand why this happened. 

I didn't write that it will fix, but it helps me to see where is problem. I guess, you copied your content from other site. This is problematic area https://www.screencast.com/t/X6hFuvsShp

It has a lot of trash code

Okay, I disable BW minify plugin and it still has the same issue. I've updated the post again, but still all the same.

What should I do?

Can you have a look?

in the same place where you enabled it in Plugins pages

Where I can Disable BW minify plugin? And why does it happen only with this post?

Disable BW minify plugin
