Access your site's FTP, copy the .htaccess file (-a is the filter to display hidden files if you don't see it listed). If after temporarily removing the .htaccess file your site still redirects then it's a scripting language. If it does stop redirecting post the code inside the .htaccess file. Don't forget to put it back and be very careful about changing it until you've gained the knack for editing Apache configuration. I would recommend testing locally on your personal computer using XAMPP which is an out-of-the-box solution, you can access the local server once you set it up at h t t p : / / localhost / (without spaces).
