Hi Tim, That error should only occur when the validation of the map= parameter fails. Did you try MS_MAP_PATTERN "." in the CONFIG? Do you have any other security settings in the CONFIG such as MS_CONTEXT_BAD_PATTERN or MS_MAP_NO_PATH? Are there any URL rewrites happening which could affect the map= parameter?
