We cannot trouble shoot this kind of things without a link to the site.
If you want support, you need to setup a test site online that we can access. You can install wordpress in a subfolder of any site you maintain and clone your site there for that purpose.
Then provide a link to your page showing the problem.
But you also need to be a lot more specific about what you are trying to achieve, and what you have done so far
Also the latest version of Xtreme is 1.2.4
