No blogs appear on the blog page

ok the blog do not appear on the blog page only 3 blogs appear (mine and 2 new), but their is 38 active blog on this site.
http://webfeminin.com/blogs/
like this one: http://etreparent.webfeminin.com/
do not appear on the blogs page.

so this is like the blogs were not exist and not associated to their owner

members can access their blog directly from their own blog via Wp-Admin on their own page
like this one for example
http://etreparent.webfeminin.com/wp-admin/

Members can connect through the main site but they cant access their blog and get this message: Sorry, there were no blogs found. on their blog page like here
http://webfeminin.com/members/coachparental/blogs/
this member is the administrator of
http://etreparent.webfeminin.com/
any ideas on how to reconnect members to their blogs? ?
