I'm using the PageCaching plugin and wanted to change my theme. When I switch themes, the items/show pages load the new theme fine and then breaks down, loading certain components of the previous theme's stylesheet (body background, header font rules and images, etc). I tried disabling and then uninstalling the plugin, and also went into the /cache/ directory of the plugin to delete those files as well (save for .htaccess). This does not help.
Can anyone figure out what's happening here?
