I just read How to delete Safari website data from iPhone by Allyson Kazamucha on 6/19/13. The steps didn't work for me. Thanks for the info but it didn't work for me. I have an iPhone 5s. I first went to the Website Data and clicked the buttons Remove All Website Data and Remove Now. I click on the Website Data again and there is still data there. So, I click the Remove All Website Data and Remove Now buttons again. This happens repeatedly and never completely removes all the data. So, I go to the Clear History and Website Data and click the Clear History and Data button. It greys out. Then, I return to the Website Data and try this again and the previous occurrence happens. What can I do?
