Fresns is an application developed on the PHP Laravel framework. Due to compatibility issues within the framework, the email plugin fails to send emails, displaying the following error message:

The "" scheme is not supported; supported schemes for mailer "smtp" are: "smtp", "smtps"

Although the framework has addressed and resolved this issue, an official release has yet to be deployed. Consequently, a temporary code modification has been implemented to accommodate this change.

File Location: fresns/vendor/laravel/framework/src/Illuminate/Mail/MailManager.php
Line Number: 197
Modification Details: Refer to the framework official fix here.
