okay so in your plugin parameters where you have the Use On/Off Switch, you have that set to true, but the Switch ID is set to 'E', this isn't right. This must be a switch Id # from your game switches. If you're going to use the 'On/Off Switch' you have to assign a switch ID and make sure that switch is set to true, otherwise if you just wanted to check if the plugin is indeed working you can set the 'Use On/Off Switch' parameter to false and test it. As long as this parameter is set to true you must assign a valid switch ID # to the Switch ID parameter and ensure that switch is set to true.
Let me know if this helps fix your issue because as it's currently configured the plugin would not function.
Edit: One other potential issue i'm seeing is your active items are '278' unless you're just trying to test with one single item which is Item ID 278 in the database. Keep in mind these IDs should be separated by a space.
ex: 2 4 6 8 10
