Hi,
seems there where no new beta releases in between which includes the fix discussed e.g. here: Community feed unusable - Greenbone Community Edition - Greenbone Community Forum or in various other threads.
The log_whole_attack isn’t available anymore from within a scan config since version 5.1.2 of the scanner:
The preference log_whole_attack is now an scanner-only preference.
