Hi guys. I just upgraded WP to 2.7 and now I can't seem to choose any themes for my site. The blog has reverted to the default theme. When I get to "Appearance and Themes" there are no themes listed even though I have Atahualpa in the "/wordpress/wp-content/themes/" folder. For kicks, I also installed a few other themes just to see if they would work and nothing. Also I tried to use the editor for the default theme and I get the message "The requested theme does not exist." Any suggestions how to remedy this? I am using cPanel to install the themes on my webhost. Please be detailed and thanks in advance.
