Gigi, I hope you have a backup!
You try this at your own risk:
- download full 3.1.6 package
-
joomlacode.org/gf/project/joomla/frs/?action=index
- install that via the extension manager.
- after that clear caches and try to update to 3.2 via the joomla update component.
All I can say is that this worked for me ...
