My RadMenu was working fine with the Rad Controls. After upgrading it to Prometheus, I get the error only on Production Server that -
Cannot use a leading .. to exit above the top directory.
[HttpException (0x80004005): Cannot use a leading .. to exit above the top directory.]

My RadMenu ImageUrl refers to ~/images/icons folder. And I checked the whole site - there is no reference to "../" for css. I had a css that was referencing images as "../" - and it was working fine. I even took that CSS out - still its giving this error.
So, what could be wrong?
