The HotCat task's preference check queries meta=userinfo&uiprop=options and looks up the hardcoded option keys gadget-HotCat / gadget-Hotcat. But the option key follows whatever id the wiki registers in MediaWiki:Gadgets-definition, and ids vary: el.wikipedia.org registers the gadget as HotCats, so the user's options contain only gadget-HotCats and the lookup finds nothing.

Steps to replicate the issue (include links if applicable):

• Log in to Starter Kit with a wiki whose HotCat gadget id isn't exactly HotCat/Hotcat (e.g. el.wikipedia.org) and HotCat enabled in your preferences.
• Open the "Install HotCat" task, step 1.

What happens?:
The card warns the gadget is disabled in your preferences, and the Continue button is disabled — blocking the task.

What should have happened instead?:
The preference card should show HotCat as enabled and Continue should be available.
