forkcms / module-mini_blog Goto Github PK

in the readme under installation, there's a link this sentence :
To download the zip-package go to the "extension page" of the module on fork-cms.com.
"extension page" :: http://www.fork-cms.com/extensions/detail/mini_blog

this link appears to be broken

I am new to Fork (installed fork and i made a theme using the theming guide) and i am trying the module guide now
(https://docs.fork-cms.com/documentation/detail/module-guide)

Installing this module gave a 500 error,
The installation proces isn't completed and if i go to edit group permissions i got following message (debug mode on)

Compile Error: Declaration of Backend\Modules\MiniBlog\Actions\Add::execute() must be compatible with Backend\Core\Engine\Base\Action::execute(): void

Where can i find how the new core works ? Because the documentation describes spoon and not Symfonie
Thanks in advance for pointing me in the right direction.
