I uploaded Genesis 2.0 and the Genesis Framework theme (the new HTML 5/css3 version), and have activated only this plugin and no others, all as a clean install at a temporary domain I own, . Unfortunately, though, the plugin does not work. When I select sidebar-content-sidebar-alt, the the sidebar-alt floats to the left, the sidebar floats below it but seems to move over to the right, and the content floats to the right of both the sidebar-alt and the sidebar.
I tried several other Genesis 2.0 themes, but they all had the same problem, so I returned to the Genesis 2.0 Framework theme. If you have a moment, I would be very grateful if you could suggest where I should start in trying to fix this - functions.php? The plugin css? Any suggestions as to where I should begin, or else what might be wrong, would be much appreciated. With kindest regards, Suuzen
