I'm getting the same error every time I try to create a new Quest game. It says "Sorry, an error occurred while processing your request." Is anyone else having the same issue and/or know how to resolve this issue? I'm still able to open up and edit an old existing game I made in the past.

You can only create new games on the secure version of the site (which also prevents people on the same wifi from seeing your password)

Check the address of the page. If it starts with http://, change it to https://.
