You moved your #laravel project to live environment but the permissions are not set correctly... here is how to fix it
Open your terminal and go to your laravel root folder, and from here we are going to apply our commands to set all folder and files permissons.
Set all Laravel file permissions to 644
find . -type f -exec chmod 644 {} \;
Set all Laravel folders permission to 755
find . -type d -exec chmod 755 {} \;
Set storage and cache permissions to 777
chmod -R 777 ./storage
chmod -R 777 ./bootstrap/cache/
Folders storage and bootstrap/cache are not accessible from outside and therefore we can set permission to read+write (777)
