sympony error disallow backend access

[javitineo]

In a Prestashop 8.1.4 (I updated it from 8.1.1 to 8.1.4 15 days ago without problems. Yesterday suddenly, while saving a product data, access to the backoffice has fallen. The front part is perfect.

 I have verified that there have been no file changes since the 30th.

 I have tried transferring the database to a twin website that I have on another site and it works.

 I have done the test of transferring the core files of a twin website that I have on another site to the one that fails and continues to fail, when the twin works.

 The error it gives is this:

Symfony\Component\DependencyInjection\Exception\ParameterNotFoundException: You have requested a non-existent parameter "cache.adapter". Did you mean this: "cache.driver"?

 

I have tried removing the cache, putting parameters in the parameters.php of everything but nothing. What do you suggest? Thank you!

I thank you for answering this on saturday.

I can't access to my backend, nevertheless I've exported the database to another "tween" website and I can see these values there. I attach them. Besides I share the ps_configuration table values.

Thank you in advance.
