FreePBX GUI broken after sysadmin upgrade

Just upgraded Free PBX from to 12.0.21.
Now after upgrading the sysadmin module from to 12.0.10, my freePBX GUI is broken and I can’t bring it up anymore.

This is where the upgrade hangs and after that, no GUI anymore.

@avayax, Is apache running? Are there overlapping ports in /etc/httpd/conf.d/schmoozecom.conf?

Sorry for the late reply and thanks for the answer.
Apache not running. Starting it returns this error:

@avayax, According to the output you provided, there is a syntax error on line 16 of /etc/httpd/conf.d/schmoozecom.conf. Resolve that and then apache should start without issue.
