[SOLVED] Can't configure theme options - I can only Reset ALL!

Hi -

I've just set up a new installation of Wordpress, added the Atahualpa theme, and I find I can't configure any of the options - the only option that ever appears is the Reset ALL theme options button, regardless of which configuration section I click on the left-hand nav.

I have actually used the reset ALL button (not having anything to lose) but it made no difference.

Is there something I need to do before I can start configuring options?

My installation was Wordpress 2.7 (which I immediately upgraded to 2.8.5 using automatic upgrade), and then I installed Atahualpa 3.4.4

I've switched themes back and forth to see if that helps. I've been able to configure other themes, but I guess config mechanisms are so different with Atahualpa that doesn't prove much.

The problem is the same in Firefox 3.5.4 and in IE8

I've searched the forums for "reset ALL" and can't see that anyone has posted about this before. Has anyone seen this before? Any thoughts or tips?

Thanks

Andrew
