Hello i am using laravel 5.7.15 i am facing issue
Make sure you hard refresh the page; Clear the cache as well by doing:
php artisan cache:clear
Make sure you have the right permissions for your logs folder:
chmod -R 755 storage/logs
Make sure to generate a key for your application:
php artisan key:generate
Check if, when using post and CSRF you have the web
middleware group wrapping your routes;
I solved mine with that! Hope it helps! :D
