Hi there, Mhuang12!
Thanks for reaching out to the Apple Support Communities! It sounds like you are having issues with Safari and opening websites. I would start with checking out the steps in this article to Clear the history and cookies from Safari on your iPhone, iPad, or iPod touch and then try opening a website again to see if you get the message again.
Here's how to clear information from your device:
- To clear your history and cookies, tap Settings > Safari > Clear History and Website Data. Clearing your history, cookies, and browsing data from Safari won't change your AutoFill information.
- To remove other stored information, tap Settings > Safari > Advanced > Website Data > Remove All Website Data.
- To visit sites without leaving a history, turn private browsing on or off.
When there's no history or website data to clear, the setting turns gray. The setting might also be gray if parental controls are set for websites. To check your settings, go to Settings > General > Restrictions, then scroll to Allowed Content.
Let me know the results and have a great day!
