Hello.
I see you are using ASPX page template. I tried it on our default
Corporate site ASPX web site template using code below and it works. No other property is needed. Code is this:
<uc3:ContentSubscription ID="ContentSubscription1" runat="server"
Path="/Products/%"
SiteName="CorporateSiteAspx"
GatewayNames="CMS.EmailGateway"
CreateEventEnabled="true"
CreateEventDisplayName="New product notification"
CreateEventTemplateName="NewProduct"
/>
Where "NewProduct" is template name as I can see it in
Site Manager -> Development -> Notifications -> Templates -> edit -> CodeName field. Could you please try this simple code and use code name of proper template? Thank you.
Best Regards,
