[Zope] "Invalid request; data was omitted"

[Edwin Martin]

Hello,

I can not post data anymore (on a live site).

Every webform I try to post, from the Zope content management page
or from my own forms, fails.

Does anyone know of a solution?

[If you've seen this mail before: sorry]

Thanks,
Edwin.
