Three sites that I've created in the past, and for whom there is no-one else administering them, have (in the last 24hrs or so) stopped showing their customised header images and replaced them with the defaults.

I have not upgraded the theme, Wordpress, or the sites before this happened.

Whats behind it and how do I ensure this kind of thing can't happen again?

Many thanks
Graham

Are you on bluehost?

No - hostmonster

Check to see if the theme was upgraded. A couple people on bluehost found bluehost upgraded their themes without prior notification or permission. And seeing as they are the same company...

Version 3.7.12 will allow you to put the logo, favicon and header images outside the theme folder.

Bluehost and Hostmonster are the same company.

Cheeky so-and-so's. Thanks guys. Now I know!

Cheers
Graham
