Mamp Pro Apache won't start on MacOS Catalina

Apache won’t start anymore.

I tried most solutions on the internet. Nothing is working.
In apache_error.log I get:

[Fri Dec 27 20:33:10 2019] [alert] Child 5905 returned a Fatal error... Apache is exiting!
[Fri Dec 27 20:33:10 2019] [alert] (22)Invalid argument: getpwuid: couldn't determine user name from uid 4294967295, you probably need to modify the User directive
[Fri Dec 27 20:33:10 2019] [alert] (22)Invalid argument: getpwuid: couldn't determine user name from uid 4294967295, you probably need to modify the User directive

Now this dude/dudette here says to reset the default

But that doesn’t help.

What to do?

    Just found the answer myself.

    Reset the templates is not enough.

    File > Edit Template > Revert all Templates to default settings…

    And then also:

    File > Factory Setting > Setting 1

    Then I set the ports back to 80… via the standard ports button.

    Now it works 🎉

    MAMP Pro 6 wants the document root for each host to be outside of /Applications/MAMP. I deleted all my old hosts, moved the root directories to /Users/me/Sites, and added new hosts with the new document roots. Then one last step seemed to be the final trick:

    File > Reset Apache Modules

    Fingers crossed. No other suggestions in other threads helped. Didn’t get any errors in the apache log file.

    For me the following worked:

    • go to ‘~/Library/Application Support/appsolute/MAMP PRO`
    • delete the file httpd.conf

    After restarting Mamp, the file gets regenerated and apache runs.

    Using the option set server ports to 80, 81, 443, 7443, 3306 and 11211 in ports & user worked for me – mamp pro 6.3.2
