While trying to create/upload a document in a document library, Ie throws the below exception 'currentCtx' is undefined what it means and how to fix this?

Is the error a server-side or client-side (script) error?

The javascript variable 'currentCtx' is declared in the core.js file and it seems that somehow java/javascript is not enabled in IE, so I have reset the IE setting and now able to perform the actionsThanks.

In my case,clearing IE cookies and temp files resolved the issue. Thanks,
