Are you running and modifications or adblockers on Firefox? This is working just fine for me, on the same version of Firefox, IE11, and Chrome 46.0.2490.86. Can you open up the console (F12) and see what it says when you load the report?

[Francesco]

Hi hsmith,
I have added the URL of my Nagios XI web console on java control panel (tab security).
Now on Internet Explorer and Mozilla FireFox the Alert Stream work properly.
On Google Chrome don’t work.
Thank you
Francesco

Can you check your java / flash plugin in Chrome? You may have multiple versions installed which can cause the page to not display.

What plugins are listed under -

Code: Select all

chrome://plugins

I believe alert stream uses Java.

Ah, the reason it isn't working is because of Chrome.

Chrome no longer supports NPAPI (technology required for Java applets)

The Java plug-in for web browsers relies on the cross platform plugin architecture NPAPI, which has been supported by all major web browsers for over a decade. Google's Chrome version 45 (scheduled for release in September 2015) drops support for NPAPI, impacting plugins for Silverlight, Java, Facebook Video and other similar NPAPI based plugins.
