MediaWiki 1.27 internal error: what is this?

[OS]

Hi,

I ran into this problem today whenever I try to access the examples/showcases and some of the features on the website:

MediaWiki 1.27 internal error

Installing some PHP extensions is required.

Required components

You are missing a required extension to PHP that MediaWiki requires to run. Please install:

• xml (more information)

It worked fine yesterday. And I got the same error both on mac and windows.

Anybody aware of this error? any fix ?

Also, when you click on more information and you go to install xml or whatever, there's nothing to install.

Thanks

Sorry about that. It was a server-side problem caused by a server update but this should be resolved now.

Best wishes,

Alfred,
what were the fixes? I ran an update on my server and got the same error however I am not at all clear on what the fix is.

Well I am running php7.1 and after a reboot it still failed.

# apt install php7.1-xml

php7.1-xml is already the newest version (7.1.7.retag-1+ubuntu16.04.1+deb.sury.org+1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

phpinfo() however showed that Apache was runing php7.0 so I installed that and it fixed things.

Dear Paul,

I'm glad to see that this solves the problem. I just had investigated what I did to fix the problem and I installed php_xml, too.

Best wishes,

Alfred
