Installed ..9.6. I change table prefix to BNR_. Installed on a remote server with no problems. 

I can do anything I like in the trail category, add topics, messages, replies etc.

I added 3 new Categories, with several forms off each category. When I click on the form to add topics, I get an message yaf_topic object not found. Every thing looks the same under the trial category and the new category I set up.

Did I miss a Key or registration or something and I am being locked out of every thing but trial category?

If this is the case, could somebody add this to the install instructions?

Many Thanks

There is an issue with one stored Procedure where the Custom Table Prefix is not used.

Go to Admin -> Database - Run SQL Query and enter...

ALTER PROCEDURE [{databaseOwner}].[{objectQualifier}readforum_addorupdate] (
    @UserID INT
    ,@ForumID INT,
      @UTCTIMESTAMP datetime
    DECLARE @LastAccessDate DATETIME

            SELECT 1
            FROM [{databaseOwner}].[{objectQualifier}ForumReadTracking]
            WHERE UserID = @UserID
                AND ForumID = @ForumID
        SET @LastAccessDate = (
                SELECT LastAccessDate
                FROM [{databaseOwner}].[{objectQualifier}ForumReadTracking]
                WHERE (
                        UserID = @UserID
                        AND ForumID = @ForumID

        UPDATE [{databaseOwner}].[{objectQualifier}ForumReadTracking]
        SET LastAccessDate = @UTCTIMESTAMP
        WHERE LastAccessDate = @LastAccessDate
            AND UserID = @UserID
            AND ForumID = @ForumID
        INSERT INTO [{databaseOwner}].[{objectQualifier}ForumReadTracking] (
        VALUES (

    -- Delete TopicReadTracking for forum...
    FROM [{databaseOwner}].[{objectQualifier}TopicReadTracking]
    WHERE UserID = @UserID
        AND TopicID IN (
            SELECT TopicID
            FROM [{databaseOwner}].[{objectQualifier}Topic]
            WHERE ForumID = @ForumID

And Click on Run Query

Bingo works like a charm!

I am extremely impressed with this product!

Many Thanks
