Issue Error : AH00543: apache2: bad user name ****

[Erwin Fiten]

Server operating system version

Debian 11.7

Plesk version and microupdate number

Version 18.0.54, last updated on July 23, 2023 03:42 PM

Yesterday I did an OS upgrade from Debian 9 to 10 (as far as I saw without an issue), and then from 10 to 11, using the howto from Plesk.
Always kept old configurations if asked for.

Now I get the following error on the start page of Plesk :

New configuration files for the Apache web server were not created due to the errors in configuration templates: AH00543: apache2: bad user name unifi. Detailed error descriptions were sent to you by email. Please resolve the issues and click here to generate broken configuration files once again or here to generate all configuration files. See the details in Configuration Troubleshooter

Don't know where to find it. the user 'unifi', the only thing this is related to, is an old subdomain I once created.

Is there a way I can figure out where this error is, and how to solve it ?
