[Ryan J Ollos]

I'm not sure what the requirements of the DiscussionPlugin are, but you can probably resolve this (at least temporarily, until the plugin author follows up with more info) by installing the TagsPlugin.

[Ryan J Ollos]

The plugin is checking whether tracdiscussion.tags.DiscussionTags is enabled, but not whether tagsplugin is enabled, which may be the problem here.

[Ryan J Ollos]

Some work was done in #8832 and #10461 to resolve these issues, but this ticket will be left open for the refactor/redesign of the TagsPlugin API implementation.

Replying to rjollos:

This has been taken care for by [12141] indeed. Let's go on tracking of details to #6783.
