upfront with fixer theme editor not functioning

Hello,

I have installed UpFront with the fixer theme, and the editor does not seem to be functioning correctly. The tools do not work the same as on the live demo of the theme. The swap/add image boxes look different and do not bring up a window that allows you to add media. I have tried to add ?dev=true&editmode=true to the URL line and that makes the theme function more or less correctly. I hope you will take a look and help me get the theme working.

Thanks!
