MediaWiki:Custom-PreloadTemplates is not a standard system message and is just where PreloadTemplates.js looks for it's config (list of templates to use).

It is mostly explained here: w:c:dev:PreloadTemplates

You need to create MediaWiki:Custom-PreloadTemplates yourself which should work with the URL (make sure you switch to source edit mode): http&#58;//yourwiki.wikia.com/wiki/MediaWiki:Custom-PreloadTemplates?action=edit
