After loading and experimenting with A 3.3.3, I loaded the theme switcher plugin to try alternative themes - including Atahualpa. It appeared to work, but I quickly settled on Atahualpa and removed the theme switching plugin to clean up the sidebar it was in.
Now my Wordpress (2.8.2) installation is very confused about changing themes with the normal admin page instead of the plugin - the Themes admin page indicates a change to a new template, but visiting the page results in using the previous template. After re-installing the plugin, it appears to be able to switch themes again, but things are still confused.
This may be a bug in the plugin, but I'd really like to understand how Atahualpa addresses it's theme files. According to the message on the WP Theme Admin page when Atahualpa 3.4.2 is activated "All of this theme’s files are located in /themes/atahualpa342", however, when I visit the page and view the Page Source, it is addressing "/themes/atahualpa" - which exists, but has earlier version of the theme. Is the directory name "atahualpa" hard wired somewhere in the Atahualpa theme? Is there a problem having multiple versions of Atahualpa loaded in a given WP installation?
Who determines where a theme's files are located - Wordpress or Atahualpa?
