The error "No hint path defined for [mail]" occurs when Laravel is unable to locate the view for the email. To fix this, you need to specify the path to the email views in the config/mail.php file.
Open the config/mail.php file and add the following line to the 'markdown' array:
'paths' => [
resource_path('views/mail'),
],
This tells Laravel to look for email views in the 'resources/views/mail' directory. If you have your email views in a different directory, update the path accordingly.
If you still encounter the same error, try clearing the cache by running the following command:
php artisan config:cache
This should clear the cache and reload the configuration files.
If the error persists, make sure that the email view file exists in the specified directory and that it has the correct file name and extension. In this case, the email view file should be named 'newlogin.blade.php' and should be located in the 'resources/views/mail' directory.
