Category:Extensions with invalid or missing type

Administrators, please do not delete this category! Administradores, favor não deletar esta categoria! Esta categoria é preenchida automaticamente por uma {{Extension}} e por isso não deve ser excluída, mesmo que esteja vazia.

This category should always be empty. Extensions listed in this category have had an unrecognized 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 extension template, but please discuss it on the talk page first.
