HTML rendering messed up in Nagios.

[sboger]

I am using Nagios XI 2024R1.1.2 with the default NCPA wizard v4.0.0.

I inherited two Nagios systems. Both are experiencing messed up HTML rendering in wizards, leading to invisible/unclickable items. Sometimes the next button just returns a blank page. Using the "Windows Server" wizard, for example I see this odd html rendering, making selection unusable, and then no "next" or "finish" buttons:

Using the "Linux Server" wizard goes through the wizard pages, and on the metrics page, there are no buttons to click forward/finish.

On the second Nagios XI system I tried to upgrade the NCPA wizard to 4.0.2 and then 4.0.4 but the issues persist.

I also tried upgrading the wizard but it didn’t work. It seems that the frontend rendering (JS or CSS) is broken after the update. Has anyone tried a rollback or patch?

Hello @sboger, @Mitchyan,

I just tested with the latest version of the wizard and everything is working properly. Is there a reason you aren't updating Nagios XI to the latest version at this time? If you just want the wizard from the latest version, you can pull down the tarball and copy the wizard files from the tarball into your installation's /usr/local/nagiosxi/html/includes/configwizards/ncpa.
