I think you may have made a mistake, because the validation that you used was an error in and of itself. There definitely aren’t “dozens of errors” anywhere….please double check and make you’ve entered the url in correctly.
I only see around 6 small errors. These aren’t really “errors” and they aren’t that big of a deal since they are just referencing multiple ID’s that are being used as backgrounds (they still work just fine). Wes actually has an update that will make them all unique ID’s, coming out soon. It’s still not really an issue regardless. The update will change – “home-feature-bg-alt” and “home-feature-bg” to different ID’s or classes.
Again, not really an issue, but Wes already has an update for this, should be out soon.
