Same error as Mike, but I'm using phpbb (3.2.7) using PHP (7.2.17), libxml2 (2.9.4), apache2 (2.4.29)
A prettier formatted error message:

I don't want to hijack Mike's post, but I think the source of the error is common. We're using apache vs nginx, so it's not the httpd. Slightly different versions of php. The same version of libxml2 though.
I'd be happy to webex with JoshyPHP to look into it in our environment.I have full server access.
