Web page displaying 'related links'

[Dennis_Brundage]

My web page worked fine until, at least as far as I know, until a couple of days ago. At that time, I was asked by a user why he only saw a page with 'related links' when he went to the web site. I checked and saw the same thing if I typed www.domain.tld. If I just typed domain.tld, the page displayed fine. In trying different things tonite, I cleared my cache and now neither url works.

I am using Parallels Plesk Panel 11.5.3. If I click the 'Preview' button on the panel, everything looks great. If I click the 'Open' button, I get the 'related links' page.

Any ideas as to what might be happening would be greatly appreciated.

--------
Update: Today, the shcnf.com link seems to be working fine and the 'Open' button in Parallels Plesk Panel works, but the www.shcnf.com link is still showing a 'related links' page.

My DNS settings show:

shcnf.com record type: A value: 198.144.188.31
www.shcnf.com record type: CNAME value: shcnf.com

I do not currently have a preferred domain set in my hosting settings. I tried setting one the other night with no luck, though I was also playing with the DNS settings (I tried setting www.shcnf.com to an A value with the IP, hoping to force it to work).

Again, any help would be greatly appreciated.

Okay, another update...using Fiddler, it seems like my page works when the server is Apache and doesn't work when it is nginx. Do I have any control over this? And, from above, do I need to set a preferred domain to get www.shcnf.com to work like shcnf.com?
