Wordpress App Access - XML-RPC

[Qoelet]

Hello,

I have tried accessing/updating my site through the WordPress app but when I ask it to search my domain it says;

"Couldn't connect. Required XML-RPC methods are missig on the server"

I've seen on a blog on the eUKHost site that the Wordpress app is recommended as a way of remote updating, so surely there is a way to get access, but I can't? Online tutorials say I need to access it through Settings > Writing from within Wordpress, but that seems to be a reduced menu as the XML-RPC option isn't there.

Any ideas on how I can get connectivity?

To fix it, I will recommend installing these two PHP packages:

sudo apt install php-xml
sudo apt install php-xmlrpc
sudo systemctl restart apache2
