Did you turn on the display of notifications in the PHP config, which was turned off earlier?

Not strong in PHP, but maybe $xml->File->trackit doesn't return an array type?
You need to debug the script line by line.

It is possible that some necessary library is not loaded during the OS update to work with XML. It needs to be installed from some common standard package or related to PHP.
