I am trying to install mediawiki 1.31 on a centos 7 machine.
I get the following error when I access the wiki:
MediaWiki 1.31 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:
- mbstring (more information)
- xml (more information)
When I try and install the extension using
sudo yum install php72-php-xml
I get a message saying
Package php72-php-xml-7.2.8-1.el7.remi.x86_64 already installed and latest version
and similar for mbstring.
Has anyone got a suggestion as to what to try, I have had a look on the internet and found similar questions with earlier mediawiki versions but nothing makes sense to me.
I am totally new to PHP, HTML etc.
thanks
Steve
