The problem still here. I has modified both "/etc/php/conf.d/com.synologycommunity.packages.cops.ini" and "/etc.default/php/conf.d/user-setting.ini"

Error message from COPS
Check if Calibre database file exists and is readable
File /volume1/Books/metadata.db not found, Please check

The open_dir setting has been detected by COPS, but it seem to be that the metadata.db cannot be found.
