The integration between Toolset and Divi theme makes it easy to add custom content to Divi and display it, on the front-end. You can use Divi Builder with Toolset to design templates for your custom post types and archive pages.
The issue here is that the customer wanted to know if he was able to have multiple site keys.
Solution:
With a basic account only the creation of 1 key is allowed. However you should be able to download the plugins and manually install them on your dev site.
With our other Account Types Agency and Lifetime you are able to create an unlimited amount of site keys.
Problem:
The Events Calendar conflicts with Toolset Layouts. It will display nothing when the Toolset Divi Integration is activated, it only shows white blank page. When we deactivate Toolset Divi Integration plugin, the calendar display properly.
Solution:
This happened because something is wrong in database table or database records are corrupted somehow or WP core files were corrupted due to which it was showing white blank page.
1. So we recommend to either fix the WP installation or install a fresh WP site and move your site content, plugins and themes there manually using WordPress export xml tool and Toolset Module Manager.
