WrongTrac, see ​TracHacks:ScrumBurndownPlugin.

Chasing the plugin name from the TracBurndown egg name made me think I should really finish #5516 for the next (0.11.3) release…

If you are referring to ​th:TracDownloaderPlugin, then this is not the correct site to inquire about your issues. Most likely, the issue you are experiencing has been captured in ​th:#10725. If you are using Trac < 1.0, then you only need to install ClearSilver.
