Please review our documentation about Toolset and Divi integration:

Divi is a powerful builder in its own right, so rather than override all their custom functionality with Layouts we try to fit into their framework. Toolset only controls the content area of these pages, so you will have to do some theme customization of your own to get the site header, footer, and other elements to look as close to your old design as possible within the Divi framework.
As far as the hot property redirect, I'm not sure exactly what's going on there. You can try these steps:
- Ensure the page is published, public, and guest users have full rights to view the page
- Disable all plugins and temporarily activate a default theme like Twenty Seventeen
- Resave your permalinks
If the page begins showing up, try enabling Divi, then activating plugins one by one until the conflict is revealed.
If the page still does not show up, you can try enabling WP DEBUG as described here:
https://toolset.com/documentation/user-guides/debugging-toolset/
Go in your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:
define('WP_DEBUG', true);
Then add these lines, just before it says 'stop editing here':
ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
ini_set('display_errors', 'Off');
Try to load the hot property page again. If any server-side errors are generated, this will create an error_log.txt file in your site's root directory. Please send me its contents. Once that is done, you can revert the updates you made to wp-config.php.
