Hi there and welcome
Can you do the following please
Hold the home and power buttons on the iPad for about 10 seconds until you see the apple logo then release.
Let the iPad restart
Then Launch the Settings app from the Home screen of your iPhone or iPad.Scroll down and tap on Safari.Now scroll all the way to the bottom and tap on Advanced.Tap on Website Data. Notice here you can see how much space on your iPhone or iPad website data is taking up.Scroll to the bottom again and tap on Remove All Website Data.Confirm one more time you'd like to delete all data.
Once done, tell me if it is now functioning correctly please.
You need to hold both the Home and Power buttons please
So the power on the top and the home at the front of the screen Peter.
