enable comments

[محروم.كوم]

One of my user has posted blog and no other user can post comment except admin.
She wants to enable comment so everybody can comment on her blog.

I checked general blog setting* user group and user blog setting and everything says can post comments.
Only thing remaining is in users cp* to check if comment bkog is allowed.

As a admin how can i take care of this? please help __DEFINE_LIKE_SHARE__
