They both dump variables in the same format & style. From some articles or documentation that I'd read, it seems
The problem is that sometimes I call
dpm($var) and nothing happens, but
krumo($var) on the same script works fine. I think I'd had the same problem in the reverse circumstance(ie:
krumo($var) does not work,
dpm($var) works). Why is this so? Is there some structure that needs to be available on the particular page or script that either of these functions uses for it's display? Maybe some region or block?
