Did something change on your server? It looks like you are unlikely to be meeting XenForo's requirements as of right now. The function in question is part of the XML system which is actually enabled in PHP by default, but it looks like your server doesn't have it enabled. That needs to be enabled in your PHP setup.

OK, I think found an PHP problem:

Installing package(s) with command apt-get -y install php-mcrypt ..

Reading package lists...
Building dependency tree...
Reading state information...
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 php-mcrypt : Depends: php7.2-mcrypt but it is not installable
E: Unable to correct problems, you have held broken packages.

.. install failed!

Mcrypt doesn't exist in 7.2, though this isn't part of Mcrypt. It's probably the "php-xml" package.

 

[Robru]

Fixed problem by removing php7.2 completely and then installing it again.

Thank you.
