It seems that any place the Sitecore CM where a modal dialog would pop up has stopped working and I haven't been able to figure out why. I see the same behavior in both Chrome and FireFox. The error description is a bit more descriptive in FireFox:

Uncaught TypeError: top._scDialogs is undefined. It seems both jsnlog.js and sitecore.js are trying to call that undefined function.

It appears that dragging and dropping is also broken and I see messages in the Console about scDraggable not being defined as well.

Package Designer error in console after clicking Items Statically

Any ideas what could be causing this?

I've tried rebuilding and re-deploying. The same codebase is working correctly on our QA environment. The environment that has this issue is DEV environment.

  • Check your network tab. Are you getting 404's on some JS files?
