We are in the process of setting up a new website. I have full access to our server and mainly manage our domains through Plesk / FTP.
I've just uploaded all the files for Magento 220.127.116.11 to our new domain but no matter what link you put in, it defaults back to our suppliers homepage.
This might be obvious, but, do I need to restart the server in order for me to be able to install Magento? most guides I've seen don't mention this.
And do I need to set permissions on all the files for me to be able to install it?
Execute following query against the database on your new server:
SELECT * FROM core_config_data WHERE path LIKE '%url%';
It will show you plenty of URLs. Some of those are pointing to your old server, you should update them.
