I'm trying to add WebPartZone to existing page. I'm working with Sharepoint Designer (Site Actions -> Edit in SPD). I see a lot of ASP markup, but when Itry to add something like
<WebPartPages:WebPartZone runat="server" Title="TestZone1" ID="TestZone1"> <ZoneTemplate></ZoneTemplate> </WebPartPages:WebPartZone>
There is an error: This Web Part Zone contains invalid non-Web Part content. Use code view to correct the content, or click to insert Web Part.
How can I fix it? Or maybe there is another way to add WebPArtZones to existing page?
