The site http://broadbandandphones.co.uk works fine basically everywhere (FF, Chrome, Safari, IE, Edge etc...) however for some reason IE11 on Windows 7 will not render the site instead throwing a delightfully vague ieframe.dll/acr_error.
The behaviour is the same on 3 separate Widows 7 machines all running on different networks so I'm pretty confident it's not a simple case of resetting permissions/IE settings on the local machine, although I have tried that - with no joy!
To make things even more fun the problem seem to be somewhat sporadic, certain pages might load fine one minute but then bottom-out the next.
I'm pretty much stuck and was wondering if anyone had experience similar behaviour? Or point me in the direction of how to debug whatever is causing the problem.
