 * [@12ax7](https://wordpress.org/support/users/12ax7/) This is related to how the
   current Comet Cache codebase uses PHP Closures, which Query Monitor doesn’t properly
   recognize. We recently refactored the codebase to use PHP Traits instead, which
   Query Monitor has no problem recognizing.
 * See this GitHub issue for details:
    [https://github.com/websharks/comet-cache/issues/686#issuecomment-194457147](https://github.com/websharks/comet-cache/issues/686#issuecomment-194457147)
 * The “errors” reported by Query Monitor are just false-positives, so they’re nothing
   to worry about, but the next Comet Cache release will resolve that issue so that
   Query Monitor recognizes the methods properly. 🙂

 * And here I am thinking I found a major bug 😀
 * Great then, you guys have it all under control.
 * Rock on! 🙂
