Hello again,
I updated my xwiki instance from 3.0 to 3.1.
  I deployed the new war-file and copied ?xwiki.cfg?,
Xwiki.properties?,  ?hibernate.cfg.xml?  and
?mysql-connector-java-5.1.5-bin.jar? from the old instance. After die
update the colibri-skin was broken.  Any ideas what went wrong?
Thank you again,
Stephanie
