Sites that have been developed with the involvement of Mambo may encounter problems when submitted to search engines.
Errors such as 'We've detected that your 404 (file not found) error page returns a status of 200 (OK) in the header.' May be displayed.
An additional component is required from Mambo called 404 SEF that allows Mambo to manage the 404 error pages. The component can be found at - http://mamboxchange.com/
