1-click upgrade module?

No manual upgrade.  I followed this but getting error. Backend also not getting. enabled debug 

in /app/config/parameters.php but no error

 

Download PrestaShop 8.1.7 from official releases.

Extract and upload the new files over your old installation except:

/modules

/themes

/upload

/download

/img

/override

/app/config/parameters.php

Delete the /install folder (the new versions ship it, but you must remove it).

Log into your Back Office:

PrestaShop will detect the version mismatch.

It will run the upgrade scripts automatically (database schema, settings, etc.).

Clear cache:
