Hey guys, so to cut a long story short, I've been developing a website on wordpress (pretty big website) for the past two weeks and earlier today I changed a setting in the general settings (pretty stupid of me, but I thought, what's the worst that could happen, all I did was change the url of the actual website, I thought I could change it back if it didn't work) and now all my stuff is lost, I cannot afford to spend another two weeks on this website as it's going live sometime in a few days.
I've got a back-up, but whenever I try and put it back onto the server space, nothing happens, it just doesn't load, it does the same as before, any ideas, any tips?
