After installing SilverStripe, and setting up my site, I closed everything.
Then go to :
http://localhost:8888/EustonWorking/admin
and it goes to:
http://localhost:8888/EustonWorking/Security/login?BackURL=%2FEustonWorking%2Fadmin%2Fpages
No Idea why this is happening, as can't edit the site anymore?
