If you're not careful on non-[=MediaWiki=] wikis, it's quite possible to screw yourself up via TheProblemWithPenIsland.

For when you read the name correctly but misinterpret what it means, see JustForFun/IThoughtItMeant (for tropes) and JustForFun/IThoughtThatWas (for works). Also see JustForFun/IReadThatAs for when you misread trope and work names.
