MAMP nginx.conf - invalid number of arguments in "user"

I am having issues starting up Nginx with the MAMP Pro application. When I press start Nginx I get the following error message invalid number of arguments in "user" directive in /Library/Application Support/appsolute/MAMP PRO/conf/nginx.conf:7 looking at the configuration file > /Library/Application Support/appsolute/MAMP PRO/conf/nginx.conf I notice the following line has multiple users user rob COMPANYWORKDOMAIN\Domain Users; However changing it to just one user (rob) does not work because it gets overwritten and reverted back next time I start up Nginx via the MAMP application. I'm a bit stuck as what to do here?
