Error to access

Hy all:

Few days ago, i change my default.asp to get a table with the top posters and the last post. All was ok and suddenly after 5 days without problems i get this error trying to access

Microsoft VBScript runtime error '800a000d'

Type mismatch: 'CDate'

/forum/common.asp, line 448

My hosting service told me they didn't make changes in the host. And i only change to version 7.9 and the default.asp. I put the old one (a backup) and the problem continue.

The code of the line is this (in common.asp):

'Read in the Last Visit Date for the user from the db if we haven't already
  If Session("ViRead") = "" Then
   If isDate(rsCommon("Last_visit")) Then Session("dtmLastVisit") = CDate(rsCommon("Last_visit"))
   Session("ViRead") = True
  End If

  'Check that there is a last visit date in the db or we will get an error
  If isDate(rsCommon("Last_visit")) Then
   
   'If the Last Visit date in the db is older than 5 minutes for the user then update it
   If CDate(rsCommon("Last_visit")) < DateAdd("n", -5, Now()) Then

    'Initilse sql statement
     If strDatabaseType = "SQLServer" Then
     strSQL = "EXECUTE " & strDbProc & "UpdateLasVisit @lngUserID = " & lngLoggedInUserID
    Else
     strSQL = "UPDATE " & strDbTable & "Author SET " & strDbTable & "Author.Last_visit = Now() WHERE " & strDbTable & "Author.Author_ID=" & lngLoggedInUserID & ";"
    End If
   
    'Write to database
    adoCon.Execute(strSQL)

   End If

Please i need some help.

Thank u

ok.... i have installed again all 7.9 web wiz forums, i read about the cdate error and i replaced the lCID to 1034 (Spain). I cleaned out cookies and the forum begins to load.... i can see the logo and the navigation buttons ... and ... today is.... and the date and time... but now i get this error:

Microsoft VBScript runtime error '800a000d'

Type mismatch: 'CDate'

/forum/Default.asp, line 154

The default is the same that comes in the v7.9 forum. Have i to change anything else in this archive?.

Thank u
