Hi,
1. Try to completely
delete cookies or use the different browser.
2. You can try to remove following lines from master page (in
CMSDesk -> Content -> root -> Master page tab):
<!-- Top info -->
<div class="zoneTopInfo">
<cc1:CMSWebPartZone ID="zoneTopInfo" runat="server" />
</div>
3. One workaround is also possible - use following
style definition in your site stylesheet to hide the message:
.PreviewInfo
{
display:none;
}
.PreviewInfoLink
{
display:none;
}
