I installed this plugin and it almost seems to work. When I click the button to generate the clone I get a blank page as a result. However, the newly cloned site does exist if I go to it. However, it seems to have cloned everything except for a single table for my calendar plugin. (http://wordpress.org/extend/plugins/calendar/)
[17-Apr-2013 08:47:03 America/Denver] WordPress database error Table 'wpnelibraries.wp_84_calendar' doesn't exist for query SELECT * FROM wp_84_calendar ORDER BY event_begin DESC made by do_action('toplevel_page_calendar'), call_user_func_array, edit_calendar, wp_events_display_list
We can just manually create the table in question but I thought you might like to know of this.
We're running on IIS if that matters.
