Trying to set up W3 Total Cache to work with Cloudfront as CDN. Why am I getting this critical error?

I was trying to set up W3 Total Cache to work with Cloudfront+S3, but had trouble following a guide.



I added my access key id and the secred key, but when I try to create the distribution from the wordpress panel I just get a "failed" message.



I looked at the logs and this is what I found:



2018-11-22T01:10:19+00:00 CRITICAL Uncaught Error: Class 'DOMDocument' not found in /var/www/html/wp-content/plugins/w3-total-cache/lib/S3.php:1770

I'm unsure of where I have this problem. Did S3 changed and now it's not allowed to use an admin user for this task?



I was using this guide: https://www.youtube.com/watch?v=yaFt3lUvsH8 I get the fail at 9:54



Thanks for the help.
