I upgraded my piano-black theme from 1.5 to 2.2 and the effect was that it got rid of most all of the formatting, especially the header of pages and the actual black background. The page has the title and two columns for the posts and the sidebar but no background (it's white) nor other stylized piano-black features (like the search bar).
When I upgraded from wordpress 2.9.2 to 3.01 the effect was that the pages no longer display, they say "The requested URL was not found on this server. The link on the referring page seems to be wrong or outdated." This is very strange since they show up in my dashboard and database and they are published and the permalinks have not changed.
I might just have to go back to the old wordpress and old piano-black, but it seems very odd to me that the newer versions break things.
If you have any advice on how to make the new versions compatible with each other and not screw everything up that would be much appreciated. Thanks.
