Some people freaked out when Divi Backend Builder is missing after they updated Wordpress to version 5. By default, it seems like you can only access the Visual Builder. But in a few clicks, you can bring back the old Divi Backend Builder easily. See the steps below: First, update Divi to the latest version. Next, go to Divi > Theme Options > Builder > Advanced > Enable Classic Editor > Save Changes & you should now be able to access the old Divi backend builder. See screenshot below. If you wish to use the new Divi backend builder, then you need to Enable The Latest Divi Builder Experience as well.
