Use [~id~] for all your internal links, where ’id’ is the number you will see in the manager’s document tree after the page title (in brackets).
Are you using the base url in your template ?
Here is the solution:
1. You must use [(base_url)] tag, for example like this: [(base_url)][~14~]
2. When inserting link, you must specify protocol to "Other", see screnshot attached.
