I tried moving a project to another server but after I copy all the files and the database and try to access the new server I get the warning:
include(DOMDocument.php): failed to open stream: No such file or directory in /home/projectname/public_html/lib/Varien/Autoload.php on line 94
It makes it imposible to access either the frontend or the backend. The magento version for the project on the old server is 18.104.22.168 and the magento version for the project on the new server is 22.214.171.124. Maybe someone else encountered this error and can give an advice on where to start.
