Make sure you restart safari after you make any changes
To restart, double click on the home button and then swipe safari up to close it. Good idea to close a lot of apps like this as they could be running in the background and using up your battery
You could also try holding the sleep/wake and home button until the apple logo appears. This will restart the Iphone/Ipad
