Rendering of static page is wrong - compared to 'hugo server' command

Very new to hugo …

version v0.20.7 running on Linux Mint

hugo server seems to work OK - producing:
<new users are only allowed to put in one image - but believe me it looked ok>

where apache serves:

There are no errors in the apache log files.

I generated the ‘public’ folder - just by ‘hugo’ and copied content to the server.

Best regards,

Set baseURL.
