Blog Comment Issues

[Budget101]

Most of my usergroups do Not have the ability to add comments to the blogs, despite the fact that the permissions are set to ALLOW comments.

In each Usergroup I have the following:
Can Manage Comments within Own Blog- Yes
Can Post Comments to Own Blog- Yes
Can Post Comments to Others Blogs- Yes
Follow Blog Comment Moderation Setting: Yes

Then in admincp>vb:options> vb Blog: General>
Default Entry: allow comments- YES
Permissions & Privacy- all "Leave Comments" are set to YES

Yet The ONLY usergroups able to Post comments are Moderators.

What am I missing here??

Is there a MySQL query that I can run to auto set ALL blogs to allow comments for all usergroups??
