Hi peaple,
I'm new into this forum, and would need some help please
Here is the example:

So i have downloaded all the site content but the Diagnostic doesn't work on the local disk, i have also put all the whole website on my server thinking that it works with HTTP but No Way .
All the .js files and jquery are present, but does not work.

So if anyone can help me to get only the diagnostic system, i'll be thankfull.

Waiting for your answers please guys
