Search Engine Optimization=yes

htaccess in the links gives me duplicate names in the url class
ie
url : http:/ /www.mysite/main-communities-18/main-communities-18/just4greek-15/
Not Found

The requested URL /links/main-communities-18/main-communities-18/just4greek-15/ was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

my htaccess:

RewriteEngine On
