SLSchools: Server issue with PHP + XSLT

[RalfGesellensetter <rgx@gmx.de>]

Dear list,

some changes on the server infrastructure have been reported (people 
subdomain e.g.) - in the same turn some basic features have been 
disabled:

While PHP can still access the MySQL data base (sample:
http://www.skolelinux.no/slschools/worldmap.php)

those scripts using XSLT produce error messages, for instance the form 
to register new schools:

http://www.skolelinux.no/slschools/editschool.php

Same is the case for the list/table of schools having registered. 
Possibly the XSLT-addons for PHP are not installed anymore or have not 
been registered correctly?

Thank you for your efforts
