I've been running a WordPress blog for a couple of years, and am just looking to freshen it up. I just up[loaded a new theme from ThemeForest and now my blog has disappeared.
When I tried to preview the new theme (before creating any pages or customising) I got the "HTTP Internal Server Error" page. I can now no longer access my blog's URL http://www.photographybyfoz.com/blog/ nor the dashboard in WordPress!
How can I get my blog back, as it is not visible to any clients? I'm also worried that I have lost all my previous posts!
