I have a website developed using October CMS based on laravel. When I run the local site I get no error but when I host the website on Linux Server Ubuntu I get an error whenever I visit a plugin to create events saying:
Unable to find configuration file config_form.yaml defined for Backend\Behaviors\FormController
The error looks like below:

Is this concerning permissions? Because I tried setting the www folder 777 permissions for all user groups so what is concerning is the site is running locally without a problem.
