Hello, @IvanMTK,
I have just checked your site now and find that you are using a very old version of the theme and have missed a lot of theme updates in between your current running theme version and the latest version of the theme.
You can check the changelog of our theme here: https://xstore.8theme.com/update-history/
So you have to update the theme and Core plugin to the very latest version and then check back.
