Using third party plugin shortcode, ajax beeing blocked and alter layout

Hello.

I am using the Car Dealer theme. Although I am using this theme, my difficulties refer to more than just the theme itself, so I’ve poste my question here in the General Discussion topic.

Well, let’s go:

First of all, I need to use a third party plugin that was developed by a developer that I have contracted. That plugin defines a shortcode [dicacarros-consulta-fipe]. I need to use that shortcode In one of my pages, but I thing that the premiumpress framework is somehow blocking the shortcode from being rendered. The shortcode was supposed to generate a form for consulting car prices. An example of the plugin with the working shortcode can be viewed here: https://blog.clipti.com.br/pagina-de-teste/

Second, I need the form created by the shortcode [dicacarros-consulta-fipe] placed over the first collum in the screen. (photo attached). How can I manage to alter the layout so the form created by the plugin is rendered above that column?

And, last but not least, looks like that premiumpress is also blocking the ajax request made by the plugin’s form. All the requests are redirected to a 404 page (I’ve seen that in google chrome’s console tools, but it doesn’t work in any browser as well).
