[RCU] after upgrade; still can't index contacts

once again, after up'ing from 1.3.1 to 1.3.2, i still receive:

ERROR: SQLSTATE[HY000] [1045] Access denied for user 'roundcube'@'localhost' (using password: NO)Error 500: Error connecting to database: SQLSTATE[HY000] [1045] Access denied for user 'roundcube'@'localhost' (using password: NO)

after trying to run indexcontacts script from cli:

from within the downloaded package folder: ./bin/indexcontacts.sh (while logged in as root / or with sudo)

this always happens on each upgrade attempt and still can't make heads or tails of it. anyone have any ideas or has this been mentioned and i'm simply forgetting the fix / corrective action? Thanks everyone.

btw:

centos 7.4 mariadb 10.2.9 apache 2.4.6
