Hello I have updated our OTRS system from 2.4.4 to 3.17 in a two step increment,

All appears to be OK except that when I click on ticket properties I get the following error message

I followed the upgrade scripts exactly, it also looks like the js/js-cache is pointing to the wrong directory it is pointing to /opt/otrs-2.4.4/..../js-cache rather than /opt/otrs/..../js-cache/ 

Any help would be greatly appreciated.
