Hi
I'used the SugarCRM 4.2.1a,
I 've a question.
I've changed the file \modules\Cases\layout_defs.php so that there aren't subpanels when I see a ticket
To do this I've commented all the subpanels in the file.
But when I try to see a ticket I receive this warning:

"Warning: ksort() expects parameter 1 to be array, null given in /opt/pitg/h/SugarSuite-4.2.1a/include/SubPanel/SubPanelDefinitions.php on line 327"

How can I resolve this problem?

Thanks
Marco
