Roundcube's bin/cleandb.sh starts with '#!/usr/bin/env php'. Under cron the PATH inherited by 'su' lacked the php binary directory and contained /root/bin directories not accessible for the http user, so the job failed with "env: 'php': Permission denied" while it worked in a login shell. Determine php (PATH or /usr/local/php/bin/php) and run cleandb.sh with PATH=<php-bin-dir>:/usr/local/bin:/usr/bin:/bin from /tmp. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
