For anybody that has this issue with their iPhone or iPad I suggest taking the following steps, as it took me about 30 seconds to solve this:
1. Do your usual checks, like power off/on, and if you can update, do it via your iPhone or iPad (don't connect to iTunes on your Mac or PC as you'll hit a wall).
2. Take the following command path from the home screen: Settings > Safari
3. From here do as prescribed below:
- Enable Do Not Track
- Clear History and Website Data (This is a blue text that appears separately in this menu)
- Limit cookies for the time being by blocking them all.
4. Enter Advanced settings located as the last item on the Safari menu
5. disable JavaScript temporarily by switching it off as this is a Java-based hijack.
6.Enable Web Inspector (not necessary, but good practice)
From here you should probably close your safari window (Double click the home button and swipe up when you see the safari app)
I found this was fine and then I went and re-enabled JavaScript and Cookies and it completely eradicated the problem.
**DISCLAIMER**
I am currently running the latest iOS at the time of writing (28th October 2015) and I only completed the above steps after having completed said update.
If there are issues beyond this the likelihood is that it's not anything as easy to bypass as a Java Plug.
