Excuse me, how to solve this problem
Show your index.php and IndexController.php. Also your directory structure.
if i am right, which i suspect i am. is your controller in a namespace?
it'd be nice if you can post your code so we can have more confidence to figure it out. Perhaps it's the acl create an infinite loop (if you're using acl).
Not sure if this was the same issue the above was having, But after registering my namespaces i missed the $di injection fo the namespaces.
$di->set('dispatcher', function () {
$dispatcher = new Dispatcher();
$dispatcher->setDefaultNamespace('Join\Controllers');
return $dispatcher;
});
