I recently bought a new membership and the SP Page Builder Pro which is the latest version, however it does not work despite no error message during the installation. What it does not work is that basically when I enter a page content to edit through SP Page Builder, only top menu is being loaded and the site looks empty, so there is nothing to edit, as if the page is empty, in reality it is not empty, it is loading on the web.

As a side note, I cleaned the cleared the cache, I tried different browsers etc.. so no change in results, all empty pages.
