Tag Icons suddenly converting underscores to dashes in slugs, breaking the icon

AquaL1te

I’ve set the following, and that worked really well. But since a few weeks it doesn’t work well anymore.

So these tags should all look like below, and they do, in the sidebar, but not in topics.

So as you can see, it works well in the sidebar, but then when I check topics and the tag overview.

Not all tags get the >> icon.

How can I fix this or troubleshoot this better?

There are more tag icons that are missing, but are configured with one in the theme component and it worked fine in the past.

I’m using the latest Discourse release (2026.5.0-latest.1 ( 4f17eef310 ) and the latest version of this theme component.

It works on my end, so I think there’s a conflict with another component or plugin. Try disabling the components to see which one is causing the conflict.

Do you have a URL to your forum? Maybe I can compare some things. Maybe the amount of tags or something like that triggers it. Because 95% of my tags work fine. I can try disabling components, but I need more time for that.

without installing this component and testing, i’m going to just guess that it is the _ underscore in the tag names. looks like all the tags that have underscores are not showing their icons.

i’m thinking this commit reconfigured your tag slugs that have underscores _ to dashes -

edit: testing now and indeed this is the case - if you change the tag slugs in this component from underscore to dash (don’t change the tag names themselves), it should work again.

That’s a strange commit, why would a component need to change that behavior? That makes things unpredictable. When I change strategic_access to strategic-access in the theme component it works in topics, but then breaks in the sidepanel.
