Sometimes Im get this kind of error when working with my plugins:
Class PluginNameAppController not found in ...
It's really weird because I connect plugin AppController before any controller using App::uses();
And this error occur randomly, then, I refresh current page (or clean tmp\cache\persistent) and it's gone.
I have 3 plugins connected in Config/bootstrap.php and I think they are conflicting some how.
Cakephp 2.6.0.
