I have a large help project containing a parent and several child projects (linked through the TOC). Output is CHM. Both the parent and child projects have many concept links accessed through See Also buttons.
In the 2022 update to this project all the concept links worked fine. However, I just updated one of the child projects and the parent project and the concept links no longer work in the updated projects. Clicking the See Also button in the CHM output displays "Selection is not associated with any topics."
When I check the source file, the See Also points to the correct concept. I made no changes to the concept or any of the associated links.
In other child projects (that were not updated) the concept links still work fine. The issue is only with the updated projects.
Any thoughts on what might be causing this and how to fix it? All help appreciated.
Thanks,
Rebecca
