Hello!
We are a business that sells stuff both in a store and online, however whenever someone goes on our website: lvlupgaming.co.uk (Not trying to plug anything, I'm just linking this for people to see) it just comes up with a Magento installation wizard, despite the fact that it's been running properly for the best part of a year.
The same happens whenever we try to access our till instore, and we don't know why this is.
Thanks in advance to anyone who fixes this!
