You can do it simply by setting a config option I have already set it
up in the Header.class.php

since uglified js provides little to no information about the location
of the error. what should we do. I checked up on source maps however
the browser support is not enough. so what do you think should happen.
I think the only way to go is to add try and catch to all the
different functions if you need to find out where the error has
occured. however adding try and catch statements to the entire
codebase will decrease code readability considerably.
