Noew we went for it more closely.
The reason was: some of the color-schemes were not found.
This was partly due to our own mistake, but strangely enough
some schemes were not found in the new distribution.
(math, gt, plus one I can't remember, as it is still missing)
Now all works fine, but the transition could have been easier.
(the change was from swiki 12 to swiki 1.1)
Thanks for your help,
