I've installed your plugin, that seems to work very well,

Hi, I've installed your plugin, that seems to work very well, but now I've this serious problem: clicking on automatic links created by WP for posts, home, pages... I'm redirected to network original subdomain, not to proper main domain's structure; main domains structure works too, but it is not automatically created into site. You can check what I mean here:

http://cyvillas.com/
if you click on sample page, you go:
http://xmodular.net/cyvillas/sample-page/
instead of http://cyvillas.com/sample-page/
(that works fine, but is not vreated automatically)
Wich way to fix? Thanks
