One of my senior writers has reported a possible bug with the Confluence macro, "Excerpt Include".
The Confluence page contains about 11 Excerpt Includes, and ever x weeks (x = I don't know, maybe 2 - 3 weeks), the Excerpt includes fail to render, and instead display the following error:
Error rendering macro 'excerpt-include' : No link could be created for [page being referenced]
When editing a broken macro, one can see that Confluence Space designation is missing. Even though it was obviously there, prior to the error occurring.
So, the editor is forced to fix each of these macros by typing part of the Confluence page name (auto complete and select).
Example:
Page Containing the Excerpt:
FY20 Mission: HR Completion - Broken 
DET:FY20 Mission: HR Completion - Fixed 
Notes:
1) The macros all break simultaneously.
2) When they break, the page history shows that no one had edited the page.
3) At first, I thought that pages with a colon (:), like the above example, might be causing the problem, but some pages have a hyphen and no colons.
