Error while displaying a tree

[jwalia]

Hi,

I am not able to see the several images in a tree. I see the following errors in fiddler

500 Internal Server Error (text/html)

However I don't see any errors  for these

200 OK (text/javascript)

Not sure how to fix the issue. Any help would be highly appreciated.

Could you find any errors in server logs? (500 error should have a reason)
