Ok I’ve updated chrome again, I updated it just a few days ago so didn’t expect there to be another one so soon. Now working with: Version 41.0.2272.101 m OS Win 8.1.
It’s only happened on the unreal engine forum, haven’t been on the ut forum in a while. Other websites work fine.
I’ll keep an eye on it now that it’s updated again, hopefully it’s been sorted.
