Hello. There are some pages (don't know how many, I can't check them all), where the notices and alerts icons do not appear. Instead, there is a regular text link to Special:Notifications, with a text "alerts (3)". For example, you can see it in w:he:special:GadgetUsage. I tried different accounts, browsers, desktop and mobile, does not help. And the same pages in another wiki project have the same problem.
Don't sure if it's indeed unbreak now. But I think it's better to set, if it really is - it's not just one page problem, so it's better to find the cause. If it isn't - remove it.
