[MediaWiki-l] [API] Can't edit with API in custom namespace

I hope someone can help. I have a custom namespace. I can edit via API in the _main_ namespace, thus, my custom bot is logging in, getting edit token, etc..  - API edit code tests good. I can edit via the WEB interface in the _custom_ namespace successfully - security/permissions configed correctly. But, I cannot edit via the API in the _custom_ namespace.  So, there is something about editing a custom namespace WITH the api. Error output: <?xml version="1.0"?><api><error code="protectednamespace" info="You&#039;re not allowed to edit pages in the &quot;SusData&quot; namespace" /></api> Any ideas? Thanks, al P.S. I can post config stuff if needed.
