You are able to change the 404 page on Yovigo. As a default we have our Oops Dragon that appears if you or a customer comes across the wrong page. In order to change this you will want to go into the backend of Yovigo. Select the 'Settings' icon on the launchpad.

 This will take you to the Settings page that has tabs towards the top. 

Select the 'Advanced' tab, on that page there will be a table, you want to select 'Manage' to the right of the 'Custom 404 Page' within the table. 

Here you will see a WYSIWYG Content Editor, this will allow you to add any content you deem necessary if a customer comes to the wrong page.
