So I have managed to capture the crash that is occurring across many different ios mobile devices with safari.
It does not appear to be a result of safari or OS versions as far as I can tell.
Here is a screen cap of the problem occurring via an emulator:
We did receive a notification from a customer today requesting the address of one of our physical locations due them being unable to access the site for a week.
I suspect this is something to do with the cache, the only reason I say this is because once the page has been loaded a few times it does appear to resolve itself?
I have combed through script safari doesn't like and compared it to what I am using for the nav and I can't see anything that immediately stands out as a conflict.
Any help or advice on this would be greatly appreciated.. I am at a total loss.
