| 40px | This Lua module is used on 13,100,000+ pages, which is ≈636732% of all pages. To avoid large-scale disruption and unnecessary server load, any changes to it should first be tested in the module's /sandbox or /testcases subpages. The tested changes can then be added to this page in a single edit. Please consider discussing changes on the talk page before implementing them. |
| 40x40px | This module is used in system messages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid large-scale disruption, any changes should first be tested in this module's /sandbox or /testcases subpage, or in your own user space. The tested changes can then be added in one single edit to this module. Please discuss any changes on the talk page before implementing them. |
| 40x40px | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
This module causes an error if any nil global is read or if any global is written to, with the exception of arg. To use, add <syntaxhighlight lang="lua" inline>require('Module:No globals')</syntaxhighlight> to the top of the module using it. The arg variable is excluded because it is necessary for Scribunto's require function to work properly. (See the Scribunto source code here.)
