'WebForm_DoPostBackWithOptions' is undefined Issue with IE 11 Only in Production server

Hi,

After login no links is working means any button .in IE 11 its showing error :- 'WebForm_DoPostBackWithOptions' is undefined

But in Mozilla no idea about issue but links are not working .I search in net that is issue because of .net 4 version but if that is the case then after deployed to QA .IN qa URL I am not facing any problem with ie 11 or Firefox . .

Only in production Url I am facing problem.

I checked with iis both are same .

I checked with weconfig file both are same .

Ajaxcontrol toolkit also same for both .

Then what else is the problem with production server .

Please help me .

Don't tell to upgrade 4 to 4.5 because in server we are not using vs. anyhow in QA server its working fine .

Please need some suggestion .......
