Hi, thanks for the swift reply.
I have sorted the console error (which i didn’t see, oops) This hasn’t effected it.
I have deleted my browser cache many times, that hasn’t helped. I can understand why you would think it was cache related and I would agree, as this doesn’t occur on my windows laptop. However it did happens on my Mac Book Pro and also a collegues MBP, and I havre tried it via Browser stack and it does it on a few browsers on there too.
I have flushed the cache for the domain and I don’t use any CDN’s, as this is basically a test environment with very little on it.
Still can’t quite put a finger on why it does on some and not others.
I have created a video to show you.
