Hello CursedChico,

 

You need to install the DOM extension. You can do so on Debian / Ubuntu using:  

sudo apt-get install php5-dom

If you get conflicts between PHP 5 and PHP 5.3 packages, you could try to see if the php53-xml package exists instead.

Note Please check PHP version before your installation. If you are using PHP7 then follow this tutorial

and finally restart your apache.

By installing two packages it will solve the issue,
