John, thanks so much. I got that DB hog down to a mere 30MB now. I will look into Task Scheduler and SQLCMD to get some db backups running at least daily, maybe twice a day. I have always been a little overboard on backups after losing a big autocad file in engineering school back in the 1980s.

Now if I could just get someone to address the other 3 or 4 major issues I am experiencing with one of my DNN installs after moving from 3.2.2 to 3.3.5. The biggest one right now is not being able to create child portals. I did lots of research on a related issue in 4.3 but I am running 3.3.5 and cannot resolve this issue.

Also, I keep getting an error when trying to create links in the FTB editor, and I get these errors in File Manager.

A critical error has occurred.
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
