I am working on this for the next version. Basically the issue is, rich editing is not defined because the user is a VB user. You can hard code this in the current version by finding these lines in vbbridge.php:
Code:
$user->wp_capabilities = $wp_roles->roles[strtolower(get_option('vbb_vbugroup_' . $vb->userinfo[usergroupid]))]['capabilities'];
$user->ID = $user->userid;
ADD this line AFTER the above:
Code:
$user->rich_editing = 'true';
What I plan on doing is adding this option (and probably more) in the vbridge user settings menu so the admin can set the default settings.
