nginx.conf appeared in all WordPress installations on folder

Late to the party but if anyone finds this as a result of a search.

By default, it will create an Nginx.conf file in the site public_html folder
you can change the location of this file in the settings.

If it is on apache it shouldn’t really do this though.
