I'm running a multi site and installed this plugin 2 days ago. Since then we have been having some issues with our wp-cron.php file bombing out. I checked our cron schedule, and there were hundreds of entries for a "clean_cache_event" to run every hour. The only reference to that name "clean_cache_event" I could find were on this plugin.
Do you remove this cron even when the plugin in uninstalled?
