Hey guys, I’m a total newb trying to migrate my Kirby site to Digital Ocean, and stumbling/learning command line stuff no the way.
On my new Digital Ocean environment, I’m getting the following error:
```
Fatal error: Method Kirbytext::__toString() must not throw an exception, caught Error: Class 'DOMDocument' not found in /var/www/blog_beta/kirby/helpers.php on line 0
```
I saw another post with a similar error earlier that solved it by installing the DOM extension, but from what I understand, the DOM extension is already enabled… (Again, total newb here trying to manage a new environment from command line instead of cPanel)
I also noticed that Kirby requires mbstring, but from what I understand, I have that enabled too.
Here is my phpinfo: [PHP 8.0.19 - phpinfo()](https://beta.meltajon.com/test-phpinfo.php)
Any ideas?

mb\_string seems to be there, but I can’t see anything of DOMDocument in your phpinfo.

Ah, I saw “DOM” listed there under “Module Authors” so I assumed it was enabled.
Total newb question that I can’t quite figure out from Google: can the DOM Extension be enabled without having to recompile/reinstall PHP 7?

Which linux flavor are using? It seems you can install php-xml like this on Ubuntu
```auto
sudo apt-get install php-xml
```

I’m running Ubuntu 16.04. I installed php-xml like you suggested but I’m still getting the same DOM error.
Here’s what the install looked like:
```
$ sudo apt-get install php-xml

Ah, restarted and it works! Thank you!
I feel like I leveled up with my command line skills lol
