| Due to a server limit of 500 "expensive parser function" calls (e.g. #ifexist:, PAGESIZE:, and PAGESINCATEGORY:), this template will only work properly if the page using it has not already exceeded the limit. When the limit is exceeded, the page using this template or module is categorised in Category:Pages with too many expensive parser function calls. (further information) |
Lua error in Module:Lua_banner at line 113: attempt to index field 'edit' (a nil value). This template outputs a category if the category exists. Otherwise, it returns nothing. It is intended for use in templates.
This template follows category redirects (using {{resolve category redirect}}).
