I need help to install WordPress and remove this host administrative privllages issue

The errors in your log are repeating like this:

2023/07/15 18:10:46 [emerg] 4380#10684: bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions)

It looks like there is still some permission or security setting from your machine that is blocking Local.

One thing you could try to get going is to change your Router Mode. Preferences>Advanced>Router Mode and switch it to Localhost.

Are you running other developer applications simultaneously? That could also cause similar issues. Apps like MAMP, XAMPP, or Docker for example.

Some other forum threads here that might help:
