Pager Error Invalid file: Pagers(slash)bs_full.php

Make sure that the file app/Config/Pagers.php exists and is in that folder.

Thank you for helping

Obviously the file app/Config/Pagers.php exists and is in that folder
and it opens fine with no errors into Visual Code (the htdocs on the NAS is a network share in my LAN)

I have copied the whole codeigniter tree from my PC to NAS and in there I have created the same apache virtual host

thoug I have edited .env file according to what eventually changed e.g. the db name and user password

The home view and others view are opening fine and also C.R.U.D. operations do work

only this view with the pager fails

P.S.
this is the phpinfo() on the NAS https://ibb.co/XCKcNtj
this is the Pager.php https://ibb.co/jvYJLbf
