Problem displaying Comments, but box is there.

Hello,

i have integrated Comments+ on my Multisite.
The Box show up on the mainblog ans subblogs.

But the comments only show up when i comment via Wordpress or Facebook.
Twitter simply does not appear on the site when i comment through this options.
Google doesnt work at all.

Maybe you have an idea what the problem could be.

If you want you can try it out here
