There was a bug in Schedules & Scoreboards v1.3 that generates a fatal error when you access your dashboard. (You will NOT see if you have the MSTW CSV Exporter plugin installed.) It has been patched in version 1.3 WITHOUT a version change, and in the development trunk. If you have already installed version 1.3, simply delete it and re-install it. If you want to load the patch without deleting and re-installing the entire plugin, simply update the plugin’s mstw-ss-admin.php file in the /includes directory with the same file from the development trunk or the new version 1.3. Sorry for the inconvenience.
