Argument #1 ($event) must be of type October\Rain\Events\Dispatcher, October\Rain\Events\PriorityDispatcher given, called in /home/c2717386c/public_html/vendor/october/rain/src/Events/PriorityDispatcher.php on line 70
This error is caused by a type hint in one of your plugin’s event subscriber classes. To find the culprit, search your plugins directory for a subscribe method with a Dispatcher type hint.
Or if you have access to the full stack trace, look for the class name just before the PriorityDispatcher.php line, that’s your subscriber.
Once you find it, change the type hint from:
public function subscribe(\October\Rain\Events\Dispatcher $events)
To:
public function subscribe($events)
This will resolve the issue.
