Getting an error using a template kit - Please help!

I’m using the kit DigiMax using Envato Elements with Elementor Pro.

Everything loads fine in the edit screen, but once I view the page, I get this error everywhere:

Undefined array key “background_color” …/wp-content/plugins/elementor/includes/conditions.php on line 87

Do you know how to fix this? I’m running it locally, so I can’t send a link.

As the items from Elements are not supported and the item support is being provided by the item author, you can purchase the item from Marketplace ( ThemeForest/CodeCanyon ) and request support from its author.
