'nextPreviousEnabled' is a new attribute on Folders.  So the schema of
folders has changed.  This means that you need to do a schema update.
Follow these steps:

- Make a backup just in case something goes wrong.

- Go to the Zope Management Interface.

- Go to the archetype_tool.

- Go to the Update Schema tab.

- I expect several types to be selected there already.  Keep those
  selections and make sure that at least ATContentTypes.ATFolder is

- In the drop down box choose to update All objects.

- Select the 'Remove schema attributes from instances' checkbox.

- Click on Update schema.  Depending on how much content you have,
  this can take a while.

I'm not sure this helps with the two versus five tabs problem, but it
should at least fix the nextPreviousEnabled problem.

Good luck,
