How to Display Webflow errors

I noticed that Webflow was displaying on the screen, the errors I have with the website I am creating. I somehow lost that display and am wondering how I can get it back so I can see the errors.
Thanks

Do you mean the developer tools? (View → Developer → JavaScript Console)

I don’t know. just started using Webflow for an HCI course. Did my mockups with Balsamiq. Too bad Webflow cannot read them.
I noticed the error messages were displayed while I was using Webflow.
