Ok,don't know wether this fixes them all, but basically what is happening is it thing you are changing the category id,even though you haven't
in post_info.asp
look for this line
bolCatIDChanged = (rsCatIDCheck("CAT_ID") <> ChkString(Request.Form("Category"), "SQLString"))
change it to
bolCatIDChanged = (cSTr(rsCatIDCheck("CAT_ID")) <> ChkString(Request.Form("Category"), "SQLString"))
