Translations:Category:Extensions with invalid or missing type/1/en

This category should always be empty. Extensions listed in this category have had an unrecognised value entered for their 'type' property, or the property was left blank. Please amend this information on the extension's page. In rare situations a new type may need to be added to the template>Template:Extension|extension template, but please discuss it on the talk>Template talk:Extension|talk page first.
