PSA will not restart - AWSTATS_DOC_D not defined?

[NETSource]

After doing update, I can no longer start PSA, I get:

service psa start
Error: AWSTATS_DOC_D not defined
Error: AWSTATS_DOC_D not defined
/usr/local/psa/admin/bin/httpsdctl start: httpd could not be started

Just applying PSA updates. Error log just says the same thing while applying hotfix.
