The problem was caused by “Composium – Visual Composer Extensions Addon” plugin, I’ve disabled it and then disabled categories via Theme Options. When that plugin is activated the next js error appears in the browser console – You can contact authors of the plugin or keep it disabled – https://prnt.sc/1qxtio8
We don’t give a guaranty for full theme compatibility with all 3-rd party plugins. Sometimes, not always, you need additionally customize the theme or plugin to make them work together. Unfortunately, it’s not possible for the author to make the theme compatible with all the existing plugins and additional customization is outside the scope of our support
