Can't access BO after update, can't find ExchangeRateProvider.php

[Sofia Sanchez]

Hi!

Yesterday I updated mi PS version and now I can't access my backoffice (front office is fine and in maintenance mode, but I get an error 500 when trying to access the BO).

I ran the debug mode and get this:

FileLoaderLoadException

Warning: include(/home/voguitos/public_html/vendor/composer/../../src/Core/Currency/ExchangeRateProvider.php): failed to open stream: No such file or directory in /home/voguitos/public_html/src/PrestaShopBundle/Resources/config/services/core/currency.yml (which is being imported from "/home/voguitos/public_html/src/PrestaShopBundle/Resources/config/services.yml").

 

Can anyone pls advise what to do now?   :S
