Have you checked ascx file for cultiv contact form control? You may need to remove <form> tag from control if this is present in masterpage

Hi

Same topic here: http://our.umbraco.org/projects/cultiv-contact-form/requests-and-questions/4411-Error-on-use---A-page-can-have-only-one-server-side-Form-tag.

Yes i know but i didin't found a solution yet.

Removing the form tag i get an error that textbox must be inside a form tag

Are you sure you've got a form runat server tag in your master page?

Part of my Masterpage:

<div id="content">
            <div class="clearall"></div>
            <form id="Contentwindow" runat="server" />
                <asp:ContentPlaceHolder id="ContentPlaceHolder" runat="server"></asp:ContentPlaceHolder>
            </form>
 </div>

is it possible to make a masterpage without that form tags and use templates under the masterpage - if yes it is new for me.
