Permission for third-party page object not working

Hi,

We have a third-party addon that uses a page numbered in the 88000 range as a web service page. Everything works in our development database, and I can open the page directly.

However, in our live database, when I try to run the page, or if the user runs a function that access the page via webserivce, we receive the error:

You do not have the following permissions on Page General Journal DP: Execute
Page Edit - General Journal DynamicPoint must close.

The license file installed in our DEV and LIVE databases are identical. The page objects are identical and were imported from DEV to LIVE. We've restarted the service tier with no effect.

Has anyone seen this type of problem before?

Thanks

Ron
