Publishing Error after upgrade from daisy-2.3-dev-r4885 to 2.3

Hi All,

I am trying to upgrade our daisy installation from daisy-2.3-dev-r4885 to 2.3. The database upgrade worked fine after checking the update statements and the wiki frontend. But when I try to publish some content I get the following error when I click publish on the screen, where I choose the Book Definition.

Error

The element type "metadata" must be terminated by the matching end-tag "</metadata>".
