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?

Update: Going to the forum admin web panel, looking for “versatile” pulled up the component, and I was able to update it from there and that cleared the message. Thanks to all for their help.

There should be a link to the theme component that’s causing the error. Discourse_docker is not the problem. [image] rbos: I searched for “htmlSafe” in the plugins and themes folders; Not sure what you’re talking about; the themes live in the database, not the filesystem, so you can’t search for them that way. If you share your forum URL (and it’s not login-required) someone should be able to help you find it.

[image] pfaffman: There should be a link to the theme component that’s causing the error. I think there isn’t. Because of an earlier post by @rbos, I took a look at https://forum.pkp.sfu.ca/ and this is what I noticed in the browser console: 80b72542d6.css:1 Failed to load resource: the server responded with a status of 403 () deprecated.js:54 [THEME 14 'Versatile Banner'] DEPRECATION NOTICE: The file 'theme-14/discourse/components/versatile-banner-column.hbs' uses the deprecated .hbs extension.

I couldn’t spot details about which component causes this message. Though starting with the versatile banner might be a good idea.

[image] Moin: THEME 14 'Versatile Banner'] I guess not a link, but it’s clear. I think you just need to get the latest version

Can you tell me why it is obvious? I clearly see that it causes the deprecation message for hbs files. But I don’t see an indicator that it triggers the message about html-safe. While it seems likely that an outdated component also causes the other messages, why do we know there is no other component causing that?

Strange. A find in the Discourse folder in the Docker container doesn’t catch a “theme-14” directory. I don’t know where that’s getting pulled in, then. I did of course see those deprecation notices, but the only one that mentioned “html-safe” was the one mentioned above.

Very interesting that it lives in the database, thanks. I am not deeply familiar with Discourse and I had assumed the theme would be in the filesystem. This is software that I touch once a year, if that. :slight_smile: (and to be clear, I am appreciative of how (mostly) bulletproof Discourse has been! It is a compliment to your efforts that I am able to become so unfamiliar with it. Software that I am familiar with is often the software I am most angry at!)
