I have deleted all Bookmarks and Cleared History in my iPad. However, when I'm in the address bar of Safari and type
www.p, a Bookmark/History shows up that I cannot delete. Can you help?
As long as the iPad is not synced with other devices which might be adding those websites in history or website data again, these steps might help.
Tap on the "open-book" type icon in Safari to reveal bookmarks tap edit to remove them.
If you can delete your history, do it!
Go to Settings-> Safari-> Clear History and website data.
Make sure that the item is not in the Reading List either.
