I cannot start Apache Web Server using XAMPP 7.2.26-0 on MacOS Mojave Version 10.14.5

I could install successfully XAMPP 7.2.26-0 on MacOS Mojave Version 10.14.5. The problem is that I cannot start Apache:

In the server events, I see this:

Starting Apache Web Server...
/Applications/XAMPP/xamppfiles/apache2/scripts/ctl.sh : httpd started
Starting Apache Web Server...
/Applications/XAMPP/xamppfiles/apache2/scripts/ctl.sh : httpd started

Exit code: 8
Stdout:

Stderr:
2020-01-07 11:33:11,210 Jaimes-MacBook-Pro.local proftpd[24257]: warning: unable to determine IP address of 'Jaimes-MacBook-Pro.local'

Do think think this is caused by an IP address conflict or something else?

UPDATE 1

Since I am not interested in ProFTPD, I am only trying to start Apache Web Server and this is what I see in the server events:

Starting Apache Web Server...
/Applications/XAMPP/xamppfiles/apache2/scripts/ctl.sh : httpd started

That would make me think that Apache Web Server started successfully. Nonetheless, I still see its status as “Stopped”.

UPDATE 2

See below the configurations that I have for Apache Web Server. I have not changed anything. I am using the default configurations.
