I have the same mistake. Found a similar solution to problems on github resources.
Really need to update javascript file WebVR.js in library three.JS!
I think it is very good issue!Also I have some problem with set with_front=>false attributes. And nothing happened with slag into url. It is still there! I looked answer for it. And just find that it is trouble with 5th WordPress. Also this question is actually! And I tried Simple CPT permalink plugin, where you can select field without permalink and it’s work! But there are couldn’t category add to url((( just postname and post_id. Can you help resolve this trouble?
