Why Does My Laravel 5.5 Registration Form Show 'The Page Has Expired Due to Inactivity'?

"The Page Has Expired Due to Inactivity" in Laravel 5.5: Troubleshooting

When submitting a registration form in Laravel 5.5, you may encounter an error stating "The page has expired due to inactivity." This issue is commonly caused by a poorly configured session driver or lack of a CSRF token.

CSRF Token Configuration

Ensure that your form contains the necessary CSRF token by implementing {{ csrf_field() }}. This token protects your application from cross-site request forgery (CSRF) attacks.

Session Driver Configuration

• Array Session Driver:

  • This driver is intended for testing only as it does not persist session data. If you're using the array driver in a production environment, your session tokens will not be validated.

• File Session Driver:

  • Ensure that the storage_path defined in config('session.files') is writable. This path is used to store session data, including tokens.

Other Potential Causes

• HTTPS Requirement with Session.secure enabled:

  • If your session.secure setting is set to true in config/session.php but your application is not using HTTPS, it can cause the "expired" error.

• Session Lifetime:

  • Check that your session lifetime is not too short. By default, it is set to 2 hours. You can adjust this value in config/session.php.

Resolution

After checking all of the above potential causes, resolve the issue by:

• Adding a CSRF token to your form
• Switching the session driver from array to file (if necessary)
• Modifying session.secure, if using HTTPS
• Adjusting the session lifetime
