I've installed Deskpro using IIS and the admin and agent interfaces are working. However, when I go to the base URL where I'd expect the user portal to be, I get a 403 Forbidden error.
I have set up URL rewriting, and I've set the correct helpdesk URL in Admin > Setup > Settings. How can I fix this?
This indicates that you need to set the default document for IIS to be 'index.php'.
This article explains how to set the default document (under "HOW TO ADD A DEFAULT DOCUMENT FOR AN APPLICATION OR SITE").
