The FeedBack has the following problem, when a vendor goes to the FeedBack tab, he see a list of his feedbacks, but he does not see the feedback details.
This is due to the control UserProfileControl, this control calcs the total of feedbacks if a property named ShowProfile is true, but this property is set to false in the method BindData() of the FeedBack tab...so the variable RatingsTotal will be 0 and the control shows - in the FeedbackDetails
In order to solve that you must change the source code, simply take the line

RatingsTotal = DataProvider.Instance.FeedBackGetCount(PortalId, -1, ProfileUserID, "AND CAT_Feedbacks.Approved = 1")

in the method Page_Load of the UserProfileControl

to out of the "If ShowProfile Then" section

Fixed in the v05.04.01, thanks!
Code is a little bit different from yours:

Dim objUser As UserInfo

objUser = UserController.GetUser(PortalId, ProfileUserID, False)

If Not objUser Is Nothing Then

Dim strTemplate As String

Dim RatingsTotal As Integer

Dim positivescore As Double = 0

Dim PositiveRatings As Integer = 0

If ShowProfile OrElse ShowFeedbackDetails Then

RatingsTotal = DataProvider.Instance.FeedBackGetCount(PortalId, -1, ProfileUserID, "AND CAT_Feedbacks.Approved = 1")

If RatingsTotal > 0 Then

PositiveRatings = DataProvider.Instance.FeedBackGetCount(PortalId, -1, ProfileUserID, "AND CAT_Feedbacks.Approved = 1 AND CAT_Feedbacks.Rating = 2")

If RatingsTotal > 0 AndAlso PositiveRatings > 0 Then

End If

End If

End If

'move to forms

If ShowProfile Then
