No new styles work and default one got messed too

[your24hourstore]

you should be able to do this, if you want to a new default style.

here i think this is a default style xml just upload this and rename it like test 1 then make it default in admincp/stylesandtemplates/ then upload it again and don't change the name when you upload. now you should have a new default style to switch back to. you can then delete the other test1

got that ?

you cannot delete your default style but you can upload a new default style as long as a default style exists

i think this is a default xml says so in the code anyways
