### **File & Folder Permissions**

Laravel needs certain folder permissions to run properly. Make sure the following folder has the correct access rights & all permissions must be recursive(must applicable to all subfolders):

* **/bootstrap**→ Set permission to **775**
* **/storage** → Set permission to **775** 
* **/public** → Set permission to **775**

For Linux or macOS, you can run:

```
chmod -R 775 storage bootstrap public
chown -R www-data:www-data storage bootstrap/cache public
```

For Windows, make sure these directories allow **write access** via file explorer or CMD.
