PRTG tabs not working (browser reports JavaScript Errors)



When I click on tab in the Sensor, like Live Data or 2 days, the tab does not change. It stays on the sensor's first tab. I get an error:

If the tabs are not working in PRTG's interface the most usual cause is that your browser runs into a syntax problem while parsing the JavaScript Code. Especially the (most-hated-by-web-developers) IE browser is more prone to these problems than other browsers.

We strongly recommend to use Chrome or FF for PRTG at any time!

PRTG's web interface is tested on various browsers (especially the official supported browsers Chrome 5+, FF3.5+ and IE8) before we release new versions, so there should be no problems, but it can still happen sometimes.

Here are some tips

If you still see this problem:

  • If you are not already running PRTG in the default English translation, please switch to English to make sure that it is not a translation problem

If you still don't succeed please open a support ticket. Please supply the following information:

  • If you can, please send us a publicly accessible URL of the page that does not work and login information. This will allow us to debug into the problem.
  • If direct access is not possible, please use the "Save page" function of IE or FF to save the current page into files and email us the files for review.

Bonus Tip

If you are familiar with Firebug on Firefox and Javascript, please run the PRTG url with Firebug enabled and you should see the javascript problem in the "console" tab.
