ମଡ୍ୟୁଲ:Webarchive
Module:Webarchive (talk · · hist · links · doc · subpages · tests (results) · sandbox ( · subpages))
 | This module is rated as ready for general use. It has reached a mature form and is thought to be relatively bug-free and ready for use wherever appropriate. It is ready to mention on help pages and other Wikipedia resources as an option for new users to learn. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing. |
This module implements Template:webarchive (talk, links, edit).
Tracking categories
ସମ୍ପାଦନା- Category:Webarchive template wayback links (୧,୯୭୭) – links to Wayback Machine
- Category:Webarchive template webcite links (୪) – links to WebCite
- Category:Webarchive template archiveis links (୮୧) – links to Archive.is
- Category:Webarchive template other archives (୧୩) – all the other archive sites that don't have their own tracking category
- Category:Webarchive template unknown archives (୧୫) – the template doesn't recognize the archive URL; this may indicate an error in the data; or the template itself needs updating to reflect a new archive site
- Category:Webarchive template warnings (୭) – soft errors that don't prevent the template from working but leave a red message
- Category:Webarchive template errors (୧) – errors typically requiring human intervention
