I called krumo() inside hook_node_load().

function mymodule1_node_load($nodes, $types) {

It works on my front page, but not on a node page. I get this error message:

Fatal error: Call to undefined function krumo() in C:\wamp\vhosts\mydrupal72\sites\all\modules\my_customs\mymodule1\mymodule1.module on line 126

Why can't I run krumo() on a node page?

  • because krumo() is not defined. – No Sssweat Mar 14 '17 at 4:53
  • Huh?? How is it not defined? Devel module is installed and enabled. Why does it work on front page but not a node page? – okey_on Mar 14 '17 at 4:56

    Try to use dsm() or dpm() instead – Yuseferi Mar 14 '17 at 6:01

An option would be using module_load_include(). Manually making sure it's loaded
