This component has broken a lot of sites that updated to 2026.1.3 ESR in the past two days.

The cause of the breakage was a missing compatibility pin. The update caused Discourse to pull the latest version of the theme component, which does not work properly on ESR.

I have made a [PR](https://github.com/merefield/discourse-tc-topic-list-previews/pull/56) that adds this pin, can you please merge it?

You can copy/paste the settings using the “Settings Editor” button at the bottom of the theme component configuration page.

> - disable the original theme component
> - add the temporary fork as a new theme component and add it to the main theme(s)
> - change the name of the new tc and add `[temp]` to it so you can distinguish between them
> - go to the bottom of the original theme component configuration page and click ‘Settings Editor’
> - select all ( **ctrl-a** ) and copy ( **ctrl-c** )
> - close the popup and navigate to the temporary forks configuration page
> - click Settings Editor, select all ( **ctrl-a** ), delete the contents ( **del** ) and paste ( **ctrl-v** )
> - click Save
