Plugin Organize Series

(WP 2.9.1)
Conflicts with I don’t know what in the admin panel.

Some pages of the admin remain blank, in particular “Modify articles”, no longer accessible. I had to deactivate the plugin.

I was really interested in the series concept but cannot take the time to see what’s wrong with it.
