Manual Update

SSH to your server, cd to your application directory and perform the following commands in that same order:

composer dump-autoload --optimize
php artisan cache:clear
php artisan route:clear
php artisan view:clear
php artisan config:clear
php artisan optimize --force
php artisan migrate --force
echo "{new version}" > storage/version.txt

Note

Replace {new version} with the installed version. E.g.: echo "v1.2.0" > storage/version.txt
