Hi!

I have a portal instance with multiple child portals and on one of the child portals, there is a link to a page with an Events module on it. The module appears correctly in View mode and the calendar events can be viewed, but when trying to edit an existing calendar entry or add a new calendar entry, it errors out with an ASP.net error.

**Note that I recently moved this portal instance from a hosting company to a private server. On the old server, you could add and edit the Events calendar data - but not so on the new server instance.

Upon closer inspection, I found that the tabid for the Events module is in a range outside of what is normal for this child portal. All of the other modules in the portal use a 28XX tabid number, but the Events module's tabid is 3891. I think this explains why data can't be added or edited in that it is trying to write to another portal's Event module. I can't explain however why it can still read data.

How can I track down which portal the #3891 tabid is coming from? I've looked through the SQL Server database for it but that is like looking for a needle in a haystack. Also, is there any way to export the data from one instance of the Events module and import it into a new instance?

Thanks for your help!
