Forum:Pages not showing up in categories

At the Transformers wiki, we've added a whole bunch of maintainance templates that add pages to specific stub categories. Simple, right? Well... they're not working.

The template's on the article w:c:transformers:Air Hunter, and at the bottom, the category w:c:transformers:Category:Character_stubs_missing_fiction shows up. But if you click on the category link, nothing shows up in the listing. I have no idea what's going on there, but it's beyond us. --Suki Brits 01:54, 17 January 2008 (UTC)


 * We've since fixed the problem. It apparently took adding a blank line underneath the template inclusion to make it work, and, uh, I absolutely do not have a single clue why that changed anything. Someone really ought to take a look at this anyway, because it's an incredibly bizarre and inexplicable issue. --Suki Brits 06:20, 17 January 2008 (UTC)


 * If you are adding categories to pages via a template, they may not show up immediately. Once you change the template, the server has to go through all the pages that hold the template and expand it in each page. Which then updates the category with that page. Because there are an number of people (several thousand) doing the same thing, this process is put onto a background job on the server. So adding a category to a template can take anywhere from a few seconds to a few hours to get all the pages updated into the category, depending upon server load, how many pages are affected, etc.
 * If you really want to see the categories updated immediately, edit the templated page in question, saving it with no changes. Tjoneslo 13:16, 17 January 2008 (UTC)
