Do you have xml module for php in your system ?? – Drudge Rajen
Note that it may be necessary to sudo service apache2 restart after installing the package. – BurninLeo

I had the same issue on Ubuntu and fixed it doing the following

apt-get install php-xml

or

sudo apt-get install php-xml

if not as root

just a minor addition to the answer. i'm using nginx with php version 7 and php-fpm. you must restart the php-fpm service in order for the updates to work, restarting nginx alone won't help
