"POST /errors/csrf HTTP/1.1" 302 5 "-" "PayPal IPN ( https://www.paypal.com/ipn )" "-"

Hello,

You need to check your server error logs.

If you have enabled ssl, please make sure that the `base_url` in `app/config/config.php` to set it to `https://`

If you need to enable app logs, you can change the `log_threshold` to 1 in above config file then visit the pages again to produce errors. Lastly check the latest error log file in `app/logs/` folder.

Thank you

The log I given is the error log POST /errors/csrf HTTP/1.1" 302 5 "-" "PayPal IPN ( https://www.paypal.com/ipn ).
It happen when PayPal send back the request can't be verified. Https is enabled and redirect all port to 443 using sectigo cert.

Only work when I disable this CSRF in app/config/config.php

```php
|--------------------------------------------------------------------------
| Cross Site Request Forgery
|--------------------------------------------------------------------------
| Enables a CSRF cookie token to be set. When set to TRUE, token will be
| checked on a submitted form. If you are accepting user data, it is strongly
| recommended CSRF protection be enabled.
|
| 'csrf_token_name' = The token name
| 'csrf_cookie_name' = The cookie name
| 'csrf_expire' = The number in seconds the token should expire.
| 'csrf_regenerate' = Regenerate token on every submission
| 'csrf_exclude_uris' = Array of URIs which ignore CSRF checks
*/
$config['csrf_protection'] = true;
```

Hello,

If you see the config `pay/[a-z]+` is already added to the `csrf_exclude_uris` You can add explicitly `/pay/pipn` if you want.

Thank you

Fixed, is that anyway to check what the updated files that you all changed when perform update?

$config['csrf_exclude_uris'] = array('pay/[a-z]+', 'admin/welcome/image_upload');

Was the payment by paypal solved? version 3.4.50 will be fine
Thanks
