Hi,

If the problem just occurs once then this usually is not a concern. What's likely happened is your browser has cached an old version of the page. When you refresh it loads the new page. The old page does not work correctly because the JavaScript files that it references no longer exist on your server. However once you refresh, everything is loaded new and working correctly, that means everything is working correctly. The best way to confirm whether it's a cache problem is to clear your browser cache first and then try to browse the page.

If the problem occurs every time when you reach that page or still occurs after you cleared the cache, then it can be a loading problem. In that case you can try to add our HttpHandler into your web.config and see if it helps:

If that still does not resolve the problem, we will need to take a look of the problem in order to find out why. In order to do so we will usually need you to isolate the problem into a test app and give us remote access to the server so that we can run additional test on it.

Thanks!
