can’t post messages..pls help

Hi - I am using wwf v 7.01 (SQL Server) I am getting problem with the posting. It is running well on my local machine, but displaying following error message in post_message.asp page when I run my forum on internet web server.

ADODB.Recordset error '800a0cb3'

Current Recordset does not support updating. This may be a limitation of the provider, or of the selected locktype.

post_message.asp, line 599

Line 599 looks like this:

'If this is a new topic then save the new subject heading and read back the new topic ID number

If strMode = "new" AND (blnPost = True OR (blnAdmin = True OR blnModerator = True)) Then

'Initalise the SQL string with a query to get the Topic details

strSQL = "SELECT TOP 1 " & strDbTable & "Topic.* FROM " & strDbTable & "Topic "

strSQL = strSQL & "WHERE Forum_ID =" & intForumID & " "

strSQL = strSQL & "ORDER By " & strDbTable & "Topic.Start_date DESC;"

With rsCommon

'Set the cursor type property of the record set to Dynamic so we can navigate through the record

set .CursorType = 2

'Set the Lock Type for the records so that the record set is only locked when it is updated

.LockType = 3

'Open the author table .Open strSQL, adoCon 'Insert the new topic details in the recordset

.AddNew (Line # 599)

I also re-uploaded the file but same problem. Any help is appreciated. Thank you.
