Hello @pczerkas

how are your saving the relevance config ? Just by clicking save on the back-office ? or you are doing it programmatically ?

Hello @romainruaud

I've tried to save relevance config from the backend (it didn't work). But the fix f160773 is rather straightforward: it adds missing parameter for parent class constructor?

Replaced by #1137

Magento constructor differs between two minor versions 2.2.5 and 2.2.6 and the order for additional parameters in constructor is inconsistent ...

See https://github.com/magento/magento2/blob/2.2-develop/app/code/Magento/Config/Model/Config.php

They introduced $settingsChecker before $data which makes us unable to have a proper backward-compatible parent::__construct() call with the $data parameter inside.
