Thanks Andrei for the prompt replay. the future is enabled and debugging is set to false but it still not working. It stop working after updated to latest framework 4.5 and then I run report Google Page Speed Insights
I have a problem regarding the javascript minification. I have set evrything, as Andrei suggested, (debug set to false and set the option from the General settings).
But when it bundle all the scripts, an error is ocurred that undefined is not a function. Basically, it has been bundled uncorrectly, but I don't know where it the problem.
I am attaching javascript like you can see below. I tried also using the scripts tags, but no success.
