Bug outlined on official Github issues tracker https://github.com/centminmod/centminmod/issues/29 Need to add Nginx GeoIP and Passenger detection on Centmin Mod Nginx upgrades. Just ran into the bug on the forum's install as Centmin Mod Nginx centmin.sh has enabled Nginx GeoIP support. Code: NGINX_GEOIP=y But when I updated the .07 beta 21 files and updated centmin.sh, it had NGINX_GEOIP=n set by default. So when I upgraded Nginx via menu option 4, it caused some downtime on the forums as there was no Nginx GeoIP module support. Going to have to add a detection routine in for Nginx upgrade menu option 4 which will check to see if existing Nginx web server has Nginx GeoIP and/or Phusion Passenger module for Nginx compiled in.
