In-page hyperlinks - headers and anchors
Publishing links - heading and anchor links
In-page links to another page in the source space are updated to published pages in the target space on publishing.
However, Confluence treats links to and from headings and anchors differently from the Confluence link types added in the body of a page.
links to anchors or headings are not updated except when they are created in macros such as the Confluence child or page tree macro
a link added to a heading in a source space page is not updated on publishing the page
The published page links to another source space page and directs you to a draft page.
Page headers with a link to another page in the source space
Links added to page heading
A link to another space page added to a page heading is not updated on the published target space page. These links are treated as absolute links.
Solution
Avoid adding a link to a page heading
If a link is required, add it to the text body of the appropriate section or configure it to the published target space page.
