Moving Prestashop 1.7 from a subfolder to root directory

[libreriasemola]

hallo

I searched through the forums, but none of the solutions given in the past is working for me.

I want to move my fresh PS 1.7 installation from /domain.com/1_7/ to /domain.com/

this is what I did:

1. backup files

2. from BO I changed base url from /1_7/ to /   (and on .htaccess file changes are applied)

3. cache was cleared

4. moved all folders and files from /domain.com/1_7/ to /domain.com/

I get white screen, either trying to access domain.com and trying to access BO.

I also cleared computer cache.

I was using memcache on a previous version of PS 1.6 I had installed in the root /domain.com/ path.   but this shouldn't prevent me to access BO.

I also use Cloudflare, but again, this shouldn't prevent me to access BO.

Error log reports:
