Can not change theme

[sango39]

Hi guys ^__^

I have the problem with my gallery : http://sango39.com/gallery

No matter how many times i try to change theme from rainy day to mac ox, the config won't save.

The admin theme remains as mac ox but the users' theme still stays as rainy day.

I would like to keep users' theme to be mac ox, what should i do ?

and one more question, how to set the default theme for user ?

I found the solution : deleting cookies 

Sorry to bother.
