My site is not loading

Hi everyone,my problem is when i type my website domain in the address bar it doesnt redirect me to my site content it shows localhost on the address bar,i have contacted my hosting provider and they said they did everything for my site to work.can someone please help me.this is my domain if you want to see exactly what i mean(www.kombochat.com).

 have you copy your site from localhost look for inc/header.inc and see your site url on line 3

root on line 18 

Did they also clear Dolphin's cache after fixing the bad domain in /inc/header.inc.php? Go into /cache, /cache_public, and /tmp, and delete all files, except for the .htaccess files.

hi camperjz i tried exactly as you said it didnt work,thanks by the way

Is the URL line in the header.inc.php file updated to use your site address (with a trailing slash (/))? If so, did you also clear your cache? If that's still not working, I can take a closer look for you. I'll need FTP access to check the files.
