WebHelp Pro output published to RoboHelp Server is missing some TOC items (for example, some deeply nested books or pages).
Back up the <RHS 8/9 Install Folder>/web-INF/WHTOCAgent/tocchunk_ie.xsl file and replace it with the downloaded file.
Delete the <RHS 8/9 Install Folder>/robo/server/resource/mr_toc_chk_ie.xsl file. If you have created more than one context, then delete all copies of the mr_toc_chk_ie.xsl file. The easiest way to delete all copies is to search for mr_toc_chk_ie.xsl in RHS 8/9 Install folder and delete all copies.
This issue occurs intermittently for large TOCs containing many books or pages. This solution is a server-side fix, and it's unnecessary to republish the projects.
