When trying to activate Dojo in the current version of WP, I get the following message:

Plugin could not be activated because it triggered a fatal error.

Fatal error: Declaration of Dojo_Silent_Upgrader_Skin::feedback($string) must be compatible with WP_Upgrader_Skin::feedback($string, …$args) in /path/to/wp-content/plugins/dojo/extensions/class-dojo-extension-manager.php on line 479

Hey Guys! I am absolutely loving this plugin. You have done an excellent job and I am looking forward to seeing what it can become. I would like to request the feature for class attendance to be tracked. Could that be possible?
