@Paladox: If you think it's fixed then you need to explain why you think so and what exactly made you think so, by a clear comment what you have tried and where.

LiquidThreads has been replaced by StructuredDiscussions on all Wikimedia production wikis (except one, which will be done soon). It is no longer under active development or maintenance, so I'm re-classifying all open LQT tasks as "Lowest" priority.

Aklapper changed the subtype of this task from "Task" to "Bug Report".Feb 15 2022, 9:39 PM
