I have created a number of pages in confluence using the Create Page macro.
All pages use the same template which has scaffolding in it.
Most of these pages I can edit and save no problems.
Some of the pages however give me an error - see image attached.

I can change the title of the page, save it, then rename the title back again and this resolves the problem.
This is ok for me, but for general users this is not acceptable. Any ideas on why this is caused and how to fix it?
Would a reindex help?
Thanks - Mick
