Can't get the domain name to appear instead of IP

Did you install dolphin before or after you setup the domain name?

Because if you installed dolphin using the IP address then that would explain why it's redirecting.

Look at your header_inc file and see what is there; may be all you need to do to get this running.  I actually migrated my site from an Apache server to the NginX server; I doubt if you need to reinstall anything.  Do you want me to take a look at things?

I would also suggest learning a bit more about the NginX configuration.

Hey Deano, Geek_girl,

Thank you so much for the replies! I guess you both were right, it's a matter of initial Dolphin config. I went to header.inc.php and edited one single line, from this:

$site['url']               = "http://192.81.213.53/dolphin";

to this:

$site['url']               = "http://mydomain.com/";

Now the browser finds the website ok and doesn't change the url back to an IP number. 

However, the website started acting as if I didn't have the rules rewritten. The two most vivid problems when the you don't rewrite rules on nginx are: 1) Profile page doesn't work. 2) in the admin panel - some modules don't work.

So I had to change how the rules are rewritten. I changed every line in the dolphin_rewrite.conf from this:

rewrite "^/dolphin/blogs[/]{0,1}$"   /dolphin/modules/boonex/blogs/blogs.php last;        

to this (removed the reference to "dolphin")

rewrite "^/blogs[/]{0,1}$"   /modules/boonex/blogs/blogs.php last;        

Now the first problem is solved - the profile is shown correctly, but the second problem is still there - some modules still don't work. The modules that don't work reside at the address of a form "mydomain.com/m/module_name/administration" while the modules that do work reside at the address of a form "mydomain.com/modules/?r=module_name/administration" so it seems very much like a problem with rewriting, but I don't know where to change that.

Thank you guys for your help!!!

clear your cache?

Let me get my Nginx configuration and send it to you by email.  Read up on the location and root for nginx config to get an understanding of how that works.  Some things are best put in the http section and not in a location.

If you are going to include each server, I suggest learning how to set up sites_enabled and sites_available; The site enabled directory holds symbolic links to the sites in sites available; when you are ready to take a site live, you add a symbolic link to the sites_enabled directory.

By the way, worker_processes will equal the number of computer cores you have, or wish to assign, to nginx; If you have a six core processor you can assign all six for niginx to use or just four.

location ~ /.ht

I would escape the .

OK, problem solved:

What caused the problem was me including the following lines in the default.conf:

# deny access to .htaccess files, if Apache's document root concurs with nginx's one 
location ~ /.ht {
    deny  all;
}

It was advised somewhere to include these lines, but I think I don't really need it, since I don't have Apache on my server at all.

Thank you all guys (and girls of course) for your support!

Did you get my emails I sent to you with the config files?

Now, Nginx does not use .htaccess files, but you can use them to deny access to a directory that contains the .htacess files as Dolphin has these in all the directories to block access to them.

I mentioned that you should probably escape the dot.  I have that in my config and my site is working as it should.  Look at the config I sent to you as I put it together from reading the top sites on configuring Nginx.
