I've looked at the code and found that there is a problem with the Access version as SQL server and Access have different fields for bolleon fields so if you are using the access version change line 195 of pm_post_message.asp from:-
strSQL = strSQL & "WHERE " & strDbTable & "BuddyList.Block = 1 AND " & strDbTable & "BuddyList.Buddy_ID = " & lngLoggedInUserID & " AND " & strDbTable & "BuddyList.Author_ID = " & lngToUserID & ";" |
To:-
strSQL = strSQL & "WHERE " & strDbTable & "BuddyList.Block = True AND " & strDbTable & "BuddyList.Buddy_ID = " & lngLoggedInUserID & " AND " & strDbTable & "BuddyList.Author_ID = " & lngToUserID & ";" |
