Cannot Find plugin and it is there

[RonnyCuba]

Hello..

Thanks in advanced for your support. I'm traying too hard to install Josegonzalez/Upload's plugin and I receive a lot of errors. I install it via Composer, Manually, I don't know in how many ways, the erros are the same: pluging not found or behaviour not found.

I really need your help.

@RonnyCuba you should do it this way:
Install

composer require josegonzalez/cakephp-upload

enable plugin

bin/cake plugin load Josegonzalez/Upload

you don't need to manually load the plugin at bootstrap
