I have the same failure after updating from 1.10.1 to 1.10.7

I'm also having this same issue. Currently searching for a way to remove these categories without using the web interface for now.

I have this issue right now. I had version 1.10.5 and upgraded via yum using opennms-stable-rhel6.repo which points to http://yum.opennms.org/stable/common

So now I have version 1.10.6 and have tried chrome/firefox/opera and the trash can does not work.

Chrome error shows: Uncaught ReferenceError: deleteCategory is not defined

Is there maybe some other way of deleting categories, that is not through the web interface?

it doesn't have a link because it's done with Javascript. I did just fix the delete code having some bad href stuff, though, so maybe that was the issue?

Regardless, I have tried the trash can in current 1.10 branch with my changes and it works, so if this still fails with latest snapshots, feel free to reopen.

Checked again with Chrome, Popups allowed for the OpenNMS IP.

Already tried to find something in the code... but i am merely a user 🙂 and java script errors can be so annoying.
