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

Hello

do you kindly have a kind suggestion for this issue?

I have an app that works fine locally

I own a NAS which has the web station

I moved the app there and there I have this weird message

Please Note: on the NAS, an updated Synology, either PHP and Mysql versions are matching my developing environment




what does it mean Invalid file? The pager works nicely on local host

Thank you
