Describe the bug

As the title of the post describes, when adding a torrent from a new tracker that isn't already on the rutorrent sidebar, a JS type error occurs, and continues to occur every time you click or do an action on the page. It also looks like another bug happens in the GUI as well:

The bug seems to go away once you refresh the page, but I figured I'd mention it here anyway.

Steps to reproduce

1. Add a torrent from a tracker that isn't already listed in the sidebar.

Expected behavior

The tracker should be added to the sidebar with no error.

Additional context

No response

No problem. The fix from trimming fool is what resolves this problem properly. You can disable the track labels plugin until v4.2.8 is released. This will remove the JavaScript error. This plugin is not required. The functionality is trivial for most people.

Gotcha, good to know. You're right, I create my own labels to separate torrents based on the tracker anyway, so that plugin is pretty redundant. I've disabled the tracklabels plugin as you suggested.

Resolved in v4.2.8.
