My company used Windchill 10.2 M030 as PLM, I found that even the function Ext.onReady() couldn't work in IE11, but FF OK.
I had tried to modify ext-all.js and ext-base.js but failed. Was anyone faced the same problem?
Go to Solution.
It should be a wrong configuration within the browser. Is js enabled in the browser? You don't have to modify any js files unless you have a customization.
Also see the setting in https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS218340, I remember facing this issue in one of the client machines.
