I updated and I am on version 2026.3.0-latest.1 and since then I have a warning
[Admin Notice] Plugin “discourse-category-custom-fields” contains code that needs to be updated. (id: discourse.resolver-resolutions)
I am using the docker version, if I understood correctly, hbs is replaced by .gjs but I don’t know how to proceed but I want to be sure that this is indeed the problem.
This one isn’t hbs related. It’s related to resolver-resolutions:
You can always find more information about the issue in the browser console.
The problem is in the discourse-category-custom-fields plugin, so you’ll need to report the problem to the author. It is a little strange, because that plugin looks like a test demonstration, rather than a real plugin. Are you sure that you need it on your site? If not, uninstalling it will solve the warning banner.
