al generar un certificado de un curso me aparece el siguiente error
line 6885 of /lib/moodlelib.php: call to core_string_manager_standard->get_string()
line 92 of /mod/certificate/type/certicadoCorporativo/certificate.php: call to get_string()
line 93 of /mod/certificate/view.php: call to require()
Invalid get_string() identifier: 'certificate' or component 'moodle'. Perhaps you are missing $string['certificate'] = ''; in lang/en/moodle.php?

no se si es cuestión de versión o de idioma o que pueda ser?
Gracias.
