Can't make Laravel 4 to work on localhost
Solution 1:
Try to change the folder permissions for the storage folder using the terminal:
chmod -R 777 storage
More info on this matter can be found here.
Solution 2:
Your errors resulted because laravel couldn't write to the app/storage folder. The rest was just a stack trace. In order to make the storage folder writable, cd into your app folder and then run:
chmod -R 777 storage
