I was testing New Blog Template with the upfront themes in my network. I noticed that the links in the menu are not moved to the new blog, but they continue pointing to the template’s pages.
I think this is because the menu items are saved as Custom links, and therefore the URLS are literal and not dynamic, even if you choose “Page/post” in the link selection in upfront.
This could be managed creating the menu in the normal wordpress backend and selecting “page” as the element type in the menu for most cases… but it will not work for links to the homepage or for anchor links like in fixer.
I hope you can help. Thank you!
