Could not create component…

Could not create component: "Settings" is not a component class as it does not implement "Aventura\Wprss\Core\Plugin\ComponentInterface". Feed to Post has been deactivated.

Cause

The most frequent cause of this behaviour is a 3rd-party plugin conflict with WP RSS Aggregator, wherein the 3rd-party plugin would declare a class in the root namespace. Then the name of that class would correspond to the name of one of our component classes.

Solution

Unfortunately, there isn’t much we can do here, due to the fact that the declaration of classes in the root namespace (i.e. without a namespace) is a gross negligence of PHP programming standards, and the only way to correct this would be for the authors of the conflicting plugin to fix this in their product.
