That's the way PHP reports about the error. The important part is the first
one, which probably means that your provider turned off the possibility
of calling external programs from PHP, thus preventing your Wiki from
running the "diff" and "patch" external executables, which are needed to
handle restores. You should check the mailing-list archives for a php-only
diff program that I think someone posted some time back.
