Re: [Trac] Re: TracHtmlNotificationPlugin only sends text/plain

Great investigation!

I'm wrong about the recent changes to the plugin in
https://trac-hacks.org/changeset/18646 .
I just fixed the issue in https://trac-hacks.org/changeset/18735 .
Could you please try the latest of the plugin from
https://trac-hacks.org/svn/trachtmlnotificationplugin/0.12/ ?

Thanks.

It seems that the plugin requires TICKET_VIEW permissions for the anonymous=
 user, in contrast to the old GenShi version, which seems to avoid tihs by =
using MockPerm (if we understood that code correctly). Do you think this co=
uld indeed be the (root) cause of the issue?
