I disabled the blog list element and the problem still exists. Also when I choose for grid layout, the problem exist. Only when i switch to another theme, the plugin works well.

There must be a conflict, but I don’t know what it is.

Is it possible to fix this problem at a manner that the plugin will work well with The7 theme? It is not an unknown theme; it has 159,819 sales.
It would be great when your plugin would work.

Well, thank you for your suggestion, but that is not really what I mean. This plugin makes a mess of my website and it looks terrible. I don’t see the difference when using this plugin or a simple free theme like twentynine. Shortcodes of WPBakery PageBuilder are shown as shortcodes on the website… It is not what I want. I need to use WPBakery PageBuilder for the effects and the general layout.

Is it possible to do a modification to your plugin on a way it does not conflict with WPBakery PageBuilder, and without loosing the layout of my website?
I asked The7 theme and they say it has it to do with wp query of the plugin? Because, when I remove the slug, the 404 error has gone, but browse to another page has no effect. It is always showing page 1, even when you select page 2, 3, etc.
