Uncaught SmartyException: Unable to load template snippet 'widgets/error/generic_error.tpl

Hallo,

ich sehe im Fehler Log oft diese Meldung.
Der Request dazu:
POST /de/widgets/PaypalUnifiedExpressCheckout/createPayment HTTP/1.0" 500

Fehler im Error Log:
Got error ‚PHP message: PHP Fatal error: Uncaught SmartyException: Unable to load template snippet
‚widgets/error/generic_error.tpl‘ in
/var/www/vhosts/myhost/httpdocs/engine/Library/Smarty/sysplugins/smarty_internal_templatebase.php:127\n

Was kann hier der Grund sein?
Wo müsste ich dieses generic_error.tpl erstellen?

LG
