No puedo entrar al BO. Agradecería ayuda

[dpo]

Buenas tardes, 

Agradecería vuestra ayuda. Tengo una web en prestashop 1.7.5.2 y ayer actualicé un módulo de pago (ets_paymentfee) e intenté eliminar un módulo que no utilizo (pago con cheque de prestashop). Tras esto, automáticamente la entrada al BO dejó de funcionar. No sé muy bien qué módulo da el error aunque tiene más sentido que sea el primer módulo.

Este es el error que me da:

(3/3) FileLoaderLoadException

The file "/home/customer/www/...com/public_html/src/PrestaShopBundle/Resources/config/services/core/currency.yml" does not contain valid YAML: The constant "\PrestaShop\PrestaShop\Core\Currency\ExchangeRateProvider::CLOSED_ALLOWED_FAILURES" is not defined at line 16 (near "- !php/const \PrestaShop\PrestaShop\Core\Currency\ExchangeRateProvider::CLOSED_ALLOWED_FAILURES") in /home/customer/www/....com/public_html/src/PrestaShopBundle/Resources/config/services/core/currency.yml (which is being imported from "/home/customer/www/...com/public_html/src/PrestaShopBundle/Resources/config/services.yml").

La web funciona sin problemas, recibe pedidos pero no puedo entrar de ninguna manera al panel de administración.

Lo más curioso es que restauro una copia de seguridad de días atrás, cuando la web estaba funcionando y me da exactamente el mismo error.

He borrado las caché pero sigue sin funcionar.

Agradecería cualquier tipo de ayuda u orientación

Gracias

Hola intenta borrando la cache pero en esta ruta

/www/var/cache/prod borras todo lo que esta dentro de esa carpeta

Buenas tardes Juan,

Gracias por tu respuesta Juan. Sin embargo, ya había borrado esas carpetas y el problema persiste. 

Si se te ocurriera alguna otra idea te lo agradecería

Un saludo

¿Puedes copiar el contenido del fichero /src/PrestaShopBundle/Resources/config/services/core/currency.yml?

Te copio el fichero aquí y también más abajo el archivo src/Core/Currency/ExchangeRateProvider.php

Por alguna razón no lee el fichero src/Core/Currency/ExchangeRateProvider.php donde sí están definidas las constantes CLOSED_ALLOWED_FAILURES
