There are a couple more steps required to get your site looking just like the demo.
Ventura comes packaged with both Divi Layout Injector and Divi Taxonomy Injector to provide a global footer, 404 page and some improved layouts for LifterLMS course category pages.
When setting up the injector plugins you will also want to add the license keys from the License Keys.txt file included with the package you downloaded on purchase.
From the sidebar admin menu navigate to ‘Settings>Divi layout injector’
In the 404 layout section select ‘Page’ and then ‘404’ from the dropdown.
In the Pre-footer layout section, select ‘Global Footer Layout’ from the dropdown
Next, from the sidebar admin menu navigate to ‘Settings>Taxonomy layout injector’
In the ‘Course categories’ section, click ‘Toggle terms’ and then select the relevant Category layout from each dropdown box. Then save your settings.
