I use ReturnOfSmartPart 1.3. I tried to use a user control which contains another user control in it and get an error "The referenced file '/CtlTest1.ascx' is not allowed on this page".
2 user controls I have. CtlTest1.ascx and CtlMain.ascx.
In CtlMain.ascx, I use CtlTest1.ascx control. Finally I want to load CtlMain.ascx in sharepoint using ReturnOfSmartPart. I get the error message "The referenced file '/CtlTest1.ascx' is not allowed on this page". Please advice me.
