Issue: "Allow Wiki Content Integration" Missing in ACP

The setting appears under Settings > Miscellaneous. It's the second setting, the one before it is "Usergroup for Wiki Moderators".

This is the full text of the setting if you need to search for it:
"Allow Wiki Content Integration
Wiki content can be placed in headers on other pages than where the original content was posted. This applies site-wide in both wiki and non-wiki areas of the site. It can be fine-tuned using other settings. Note that this will add at least 1 query on every page where wiki integration is permitted."

Thanks for the insight, pegasus, but I don't see, and I have never seen (as in: not on Gamma 4, either) any such a setting.


My Settings->Misc goes like this:

Usergroup for Wiki Moderators
*
Enable Support for Legacy Wiki Syntax
Publish Wiki Content to Facebook
Show Wiki Statistics on Forum Home?
Enable Wiki Sidebar?
Use Forum Tagging for Wiki Pages?

* is where I'm expecting to find "Allow Wiki Content Integration", according to what you say(?), but it isn't there (nor, again, has it ever been)? There's nothing, it goes right from "Usergroup for Wiki Moderator" to "Enable Support for Legacy Wiki Syntax". No missing phrases, no controls, nothing. It just isn't there.
