We have been getting a warning [subject], and I’m unclear where it’s coming from.

There’s a similar error on console:

DEPRECATION NOTICE: `htmlSafe` from ‘discourse/helpers/html-safe’ is deprecated. Use `trustHTML` from ‘@ember/template’ instead. [deprecated since Discourse 2026.3.0] [deprecation id: discourse.html-safe-helper]

I searched for “htmlSafe” in the plugins and themes folders; the only active plugin that contained it was “docker\_manager”, which I think I’ve disabled (removed plugins/docker\_manager, removed the entry from config/official\_plugins.json).

But still getting the error. Where else should I be looking?
