Can't save anything in theme option page

Hi
Thank you for your reply
Yes I’m admin. The problem is that when I modify an option in Dashboard=>Appearance=>Theme Options (with the “sliding panes”), nothing stay saved when the page reloads itself. In the same time when I look at the database there is an entry in wp_options called catchbox_options (in option_name column) with some datas stored serialized :

So I wondered if this was a problem of saving datas, or a problem of reading the datas stored once saved…
If I enter some CSS in the box “custom css”, nothing is saved either…
