Dog's breakfast

Somehow, my blog settings have been totally muddled up! I can live with it at the moment, but it's not ideal. I need to reset the template settings somehow, but not sure how to do that. Anyway, it taught me not to fiddle with these things. It didn't help when the whole background went black for a few days. I wish I understood more about computers, and how to fix things. Maybe I should do a quick IT degree.... ooops, no forget that...
