Problem with Adjuster plugin Class not found
carbonBalanceAdjuster.php should be CarbonBalanceAdjuster.php since the name of the class is CarbonBalanceAdjuster and you're probably on a case-sensitive file system, which is why auto-loading can't find it.

The same goes for your other plugin files as well.  You can use https://pluginfactory.io to generate boilerplate plugin code to help avoid case-sensitivity issues like this.
