It seems like you are loosely comparing two booleans. Considering using the strict comparison === instead.

This code seems to be duplicated across your project.

This code seems to be duplicated across your project.

            if (is_subclass_of($class, 'OSC\OM\PagesInterface')) {

Due to PHP Bug #53727, is_subclass_of returns inconsistent results on some PHP versions for interfaces; you could instead use ReflectionClass::implementsInterface.

                $this->page = new $class($this);

The variable $page_code does not seem to be defined for all execution paths leading up to this point.
