Fatal error triggered when trying to activate

Hello,

I’m getting a weird issues when trying to activate the plugin. “Plugin could not be activated because it triggered a fatal error.” After setting debug in the config file, I still get no further information to track down the error. I’m using PHP version: 5.6.17. Any help would be appreciated. I’ve been trying to track this down for a couple days.
