If you want checkwiki errors to be detected, you will also need to create and configure checkwiki configuration page.

@NicoV do you mean this configuration page instead of the link you posted?

With the configuration page, you can use WPCleaner on gom wiki, but it will be limited in features as it won't find checkwiki errors : you can edit pages, be warned about links to disambiguation pages... but not checkwiki errors.

To see checkwiki errors, you also need to configure checkwiki (it's a different project) :

• You already told WPCleaner where the checkwiki configuration file will be : it's the parameter check_wiki_translation_page in the checkwiki configuration chapter
• You need to configure checkwiki errors in this page, you can use the English configuration or the French configuration as examples (just think of replacing the _enwiki or _frwiki at the end of each variable with _gomwiki)
• If you're interested in having lists of pages with the errors, daily updated, you can then ask for gom wiki to be added to the projects handled by checkwiki (example of request)
