Why Is My Laravel 5.5 Registration Form Showing a 'Page Has Expired Due to Inactivity' Error?

"The page has expired due to inactivity" Error in Laravel 5.5: Troubleshooting Inactivity Expiry

When submitting a registration form in Laravel 5.5, you may encounter the error "The page has expired due to inactivity." Despite the presence of the CSRF token, this issue can arise if certain configurations or settings are not properly set.

Possible Causes and Solutions:

1. Incorrect Session Driver:

The session driver is responsible for storing session data, including CSRF tokens. If the session driver is set to "array," which is intended for testing purposes, it will not persist session data between requests. This can lead to the "page has expired" error. Switching the session driver to "file" or another persistent driver should resolve the issue.

2. Inactivity Timeout:

Laravel's CSRF token validation may expire after a certain period of inactivity. By default, this timeout is set to 120 minutes, which means that if the user takes longer than 120 minutes to submit the form, the CSRF token will become invalid and the error will occur. To resolve this, you can increase the CSRF token expiration time by modifying the config('session.lifetime') configuration setting.

3. Incorrect Storage Permissions:

If you are using the "file" session driver, it may be that the storage_path specified in the config/session.php file is not writable. This can prevent Laravel from storing session data properly and lead to the "page has expired" error. Ensure that the storage_path is writable and has the correct permissions.

4. HTTPS Configuration Mismatch:

If your session configuration in config/session.php has the secure and domain settings enabled, but your development environment is not using HTTPS, this can also cause the error. To resolve this, disable the secure and domain settings in the session configuration or ensure that your development environment is using HTTPS.
