Ok Looks like I have to do it all again! fasthost do not do any backups that I can use!
I am no programmer/internet person, and WordPress is a easy system to use to make and keep you website up to-date, BUT I feel and there is MANY OTHERS (just search in support) who found it far to easy to change a theme to the WHOLE website, to find they don't like it and can't go back the theme they had before. with out having to call/contact there hosting company and ask for a back up, if they have one!
Or having to redo there heading/sidebars and put things back in order.
I would of thought it would be good to have a system that can undo a mistake/change easier. Or ask again if you really like to change the WHOLE site theme. (like when you delete something is ask are you sure!)
