Safari cannot open the page because the address is invalid

Umm you don't download apps in Safari.

I know that. The apple store app gives the choice upgrade or quit. Press upgrade and I get can't open upgrade page because of invalid address

Just what are you doing from what app?

What does Safari have to with this?

I sounds like you are have a link on a webpage and that if on a computer it will open iTunes and go to the app. That does not work on the iPod. You have to start in the App store app.

I am trying to download the find my phone app and sync my devices, an iPhone 5 and an iPad 2. I tried to tap the icloud in general setting but there is no icloud there. When I tried to download the find my phone app from the apple store I got a message to Upgrade or Quit.. When I tapped Upgrade i got the safari can't find page because of a invalid address. First how do I get icloud into my settings menu?

Did you ever setup an iCloud account? It is different than your Apple iD/iTunes account but can be related.

See:

The Appstore/Safari error could be related to other App store problems if you have iOS 6.

While looking at a photo on photobucket.com I got the pop up message "Safari cannot open the page because the address is invalid". The pop up will not go away and so I cannot use Safari. I shut down the iPad and restarted and in the second before the pop up appeared managed to delete the photobucket.com address, but the pop up still appeared even though there is no address shown. Incidentally I notice someone else had the problem in connection with photobucket. Maybe I have to delete Safari and reinstall, though there may be a file on the iPad that will not be eliminated this way.

It seems to be caused by Javascript. If you disable it in settings/safari the pop up window will not appear. However the drop down menus etc will not work without Javascript. Best option is to download "Chrome" or "Mercury" or wait for Photobucket to fix it:)

If you enable the "De Bug" console it will sometimes work. I am currently using an Ipad 1 with OS 5.1.1 but the problem also happens on an Ipad 3 with OS 7
