Help! Blog disappeared

Hi

I'm hoping you can help as my blog has disappeared. I updated it the opening blog page yesterday and today it's a blank. I can't even login. I can access files via FTP. (blog.camerajazz.com)

I have the blog set to email me a backup every Friday. Today I received the 'database' backup, but not the 'theme' backup. (I've never had to use the backups before).

I did get one pingback (sorry I've no idea what those are) yesterday afternoon

this is what it said - I apologize if it's completely irrelevant

New pingback on your post #22 "Funshops"
