[Plugin: SharedItems2WP] Can install but not actually run the plugin

Hi,
I’ve been trying to use SharedItems2WP for a while now. Installing and configurating works fine, but it wont actually post any shared notes. When I try to “run now”, Chromium gives me the message “Server error.

The website encountered an error while retrieving http://www.isakgerson.se/wp-admin/options-general.php?page=SharedItems2WP.php. It may be down for maintenance or configured incorrectly.”

This is how my configuration looks: http://image.bayimg.com/badkcaadi.jpg . Except for “Shared items url”, “Title” and “Category”, all is unchanged.
