Cannot submit a guest comment

Hi,

I have EasySocial, EasyBlog, EasyDiscuss and Kommento, and am trying to inegrate this all together.

At the moment, it seems just impossible to post a comment as a guest on a blogpost, I get an error displaying not much to go with:

Status:
200
Status Text:
OK
Response Text:

I hope I have all settings correct, I am trying to get Kommento to handle the comments on EasyBlog, and it should be possible on our site for both guests as registered guests, to add a comment.

what am I doing wrong?

additional info:

my EasySocial members of specific profile types should be able to post blogs with EasyBlog. They should also be able to comment on blog posts of other members, and of course on comments made on their own posts (so comment on comment).

Visitors of the site may post comments on blogs without signing in, or by registering. If they register, I want them to be able to post comments on EasyBlog items, and be able to respond to, or create topics in EasyDiscuss.

Those visitors can sign up through EasySocial, or Joomla default, I do not know what is best. I did create a profile type in EasySocial, specifically for this group, and set it: "do not show up in EasySocial listing", as I do not want them to show up with their profiles in searches for EasySocial members.
But, lso that is not working the way I want to, when registering while trying to comment on a blog post, it gives me the EasySocial registration of the wrong Profile Type.

Any help on that would also be appreciated!

Corine
