@leocg Problem solved, thanks to You! 🙂
When All extensions were disabled ~ Disqus works.
I enabled one after another. Suddenly Disqus stop to work.
So I disabled it again, and continue to enable the extensions. All works with Disqus, so it was just one. That extension was not from Avast software. A fake from the real one. (See my picture!)
So ~ Problem solved!
