Found the problem.

 

Change the following code:

    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here

        Editor1.LoadHtml("~/Templates/career.html")
        Editor1.HelpUrl = "http://localhost/brousaCMS/Help/help1.aspx"
    End Sub

    Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click

        If Not txtFilename.Text Is Nothing Then
            Editor1.SaveFile("~/brousaCMS2/doc/career/" & txtFilename.Text & ".html")
            btnSubmit.Visible = False
            Editor1.Visible = False
            lbSubmit.Visible = True
            Panel1.Visible = False
            Label2.Visible = False
        End If

 

to:

 
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If Page.IsPostBack Then
             If Not txtFilename.Text Is Nothing Then
                Editor1.SaveFile("~/brousaCMS2/doc/career/" & txtFilename.Text & ".html")
                btnSubmit.Visible = False
                Editor1.Visible = False
                lbSubmit.Visible = True
                Panel1.Visible = False
                Label2.Visible = False
            End If
       Else        
            'Put user code to initialize the page here

            Editor1.LoadHtml("~/Templates/career.html")
            Editor1.HelpUrl = "http://localhost/brousaCMS/Help/help1.aspx"
        End If      
    End Sub
