What do you do when you delete your 'Theme' by mistake? can you get it back or is it a case of nope
even when it's the default
You can have a look in the folders inside the ./cache/themes/ folder and see if the CSS files didn't get deleted for some reason, but otherwise, no, deleted means deleted. However you can get the default back by clicking Create New Theme on the Themes page.
thanks, just done it - thanks - heart in mouth job
