I am using WP 2.3.1 (my hosting service will not allow me to upgrade) and have installed Atahualpa 3.3.2. I'm having a problem with my widgets. When I add or update a widget and click "save changes," nothing happens. Is there a fix for this? I like the theme a lot but this has to work or I'll have to go back to the drawing board.

Does your hosting company prevent you from installing a newer version of WP? ie. My hosting company will only automatically install up to a certian release, but I was able to do it manually. If they won't let you upgrade, I would back up my database and the content of the wp-contents directory and anything else I had stored there and I would find a new hosting company.

You will have problems with Atahualpa 332 running on WP 2.3.1, if uses functions that do not show up till WP 2.5 I would move up to the latest WP - 2.8.1 as of now.
