Fresh install and all went fine (following the very good "how to")
At installation I choosed ngix, then  ctrl+c and restarted installation choosing apache.
I have now two problems, nginx starts anyway, always as first, obviously apache finds the port busy, but I would like to run only apache2. With google i found:
sudo update-rc.d -f nginx disable
Is this the correct command to disable ngix at boot ? 

First problem
I noticed that with nginx I cannot access cluebringer:
2015/02/22 22:02:02 [error] 1262#0: *145 "/var/www/html/cluebringer/index.php" is not found (2: No such file or directory), client: xxx.xxx.xxx.xxx, server: _, request: "GET /cluebringer/ HTTP/1.1", host: "xxx.xxx.xxx.xxx"
While with apache works ok.
xxx.xxx.xxx.xxx - postmaster@mysite.net [22/Feb/2015:23:53:53 +0100] "GET /cluebringer/tooltips/bt.css HTTP/1.1" 200 767 "https://xxx.xxx.xxx.xxx/cluebringer/" "Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; rv:11.0) like Gecko"

Second problem
Awstats
With apache I get the login popup, while with ngix the page is free for access, no login required !!

So would like to fix it and keep ngix but use it as backup resource for web access(in case I mess-up apache), but I would like to use apache primarily.
All the rest is working ok !!
Thanks
