please help me! (getElementsByTagName)

Hello, I made my company web site using Dhtmlxsuit PRO Enterprize.
I test IE11.
I get the following error:
Object dose not support this property or method ‘getElementByTagName’
So, I’m debuging some codes.
here are my codes.
else if(c[0]==“”)d=(this.xmlDoc.responseXML||this.xmlDoc).getElementsByTagName(c[e].replace(/[[^]]*]/g,“”)),e++;else return[];

how can I solve the problem?


IE11 is supported since the dhtmlx 3.6 build 131023.
Please, try to update the version of your dhtmlx.
