htmlspecial chars does not work on server

Hi, I just uploaded the perfect working site to the server, but suddenly htmlspecialchars does not seem te work there, so a lot of errors if people put entries with " and ' in the guestbook. The server is a cobalt raq server, build with: './configure' '--prefix=/usr' '--with-apxs=/usr/sbin/apxs' '--with-gd' '--with-gettext=/usr' '--enable-safe-mode' '--with-config-file-path=/etc/httpd' '--with-exec-dir=/usr/bin' '--with-zlib' '--enable-magic-quotes' '--with-regex=system' '--with-ttf=/usr/lib/libttf.so' '--enable-track-vars' '--enable-xml' '--disable-debug' '--with-libdir=/usr/lib' '--with-db3' '--with-interbase=shared' '--with-mysql=shared' '--with-pgsql=shared' '--with-ldap' '--with-imap' I presume it has something to do with --enable-magic-quotes... Anybody with experience with this? Tnx, Martijn
