I have had a few people tell me that when trying to visit a site using safari on their iPhones, they get an error that says:
Safari cannot open the page because the server cannot be found.
I asked other people to test on their iPhones and they said it works fine. After asking Google about this it seems that the answer is always something to do with the phone itself. But, it is not realistic to ask everyone with an iPhone to check this setting, and check that setting in order to try use the website.
Does anyone have any suggestions regarding this?
