Mary you need to login to your server via FTP or Cpanel

go to the folder where software is installed. 

go to ow_includes folder of the software

open config.php file

what do you have there for HOME URI? the domain name should be without index.php at the end. 

If you don't have index.php at the end of your domain name in config.php file, make sure you have default .htaccess file in the root of the software, make sure it is not empty. 

If everything is ok, please contact your hosting provider and make sure you have mod_rewrite module enabled and properly configured. 

Thank you for helping everyone! I have this....

<?php
define('OW_URL_HOME', 'http://worldwideddnetwork.com/');

And here is what i have in my atp access file

deny from allOptions -Indexes

Where exactly do you have a redirect loop? I just visited your site it opens without any redirect loop. If you want I can show you screenshot. 

i know my hosting company said the same if you try to click on a members profile it takes you to a redirect loop

No, it does not, see screenshot. 

Hmmmmm how odd perhaps it is my computer then.

Try to clear your browser cache or try different browser. 

ok i will do that thank you
