"cannot bind to port 8080" when trying view two apps at a time?

I am simultaneously creating the dracula blog and the animal shelter page as Michael suggested. However, when I try to view my animal shelter blog with Mongoose I get an error about not being able to bind it to the port number. I'm guessing it's because the dracula blog is already using that port, but is there a way to change that?

I even tried closing the dracula page and opening mongoose in animal shelter folder, but I still got the same issue and it just linked back to the dracula page. Any idea what's going on here?

Have you tried going into Edit Configuration for Mongoose and changing the listening port?
