When running 'Make Includes' via the ACP, it returns a list with items coloured in red. I can't remember for sure right now, but I believe they have been green in the past. Looking at the code [1], it seems they are only painted green 'if (is_writable($tmpFile))'. These include files reduce the need of database lookups, but I don't know to what extent this may be an actual problem. That said, if this 'tmpFile' is not writable, I suspect it could mean that this is not the only issue lurking about. 1. https://gitweb.gentoo.org/proj/forums.git/tree/htdocs/admin/admin_mkforums_includes.php?h=forumscvs#n174
