Why wont any of my themes work? My clients get errors when they try to activate themes.

Im not sure whats happened but most of my themes are giving me this error message when my clients try to activate them. Help please? Im not sure whats causing this. They were fine when I last signed in. I was fiddling with domain mapping on one site but I dont htink athat would affect all the sites on my install likes this.
