Apache2 does not start after OS upgrade

Hello,
opensuse LEAP 15
linux 4.12.14-lp150.11-default x86_64
apache2 2.4.33

On opensuse v42.3 apache2 v2.4.23 worked fine. On opensuse 15.0 apache2
v2.4.33 refuses to start.

Below is all of the info I could find regarding its failure to start.
The bit about "unit configuration" seems helpful, if only I knew what it
meant.

The part about "<whatever>_module is already loaded, skipping" was
listed in LEAP 42.3 as well. I could never find why apache would try to
load the modules twice but it was not a deal breaker.

Suggestions?

$ systemctl start apache2.service
Job for apache2.service failed because the service did not take the
steps required by its unit configuration.
See "systemctl  status apache2.service" and "journalctl  -xe" for details.
