I set up a new WordPress site over the weekend. Several times, I checked the site and was greeted by a splash screen with icons from all of the major browsers and a message indicating that my browser was no longer compatible. I have the current versions of IE, FF, Opera, Safari, and Chrome, all of which are the current versions, and they all return the same result on all computers I try it on. Once I turn off the cache, everything returns to normal. I have tried resetting the cache settings to default and deleting the cache files via the Dashboard, but the problems returns, sometimes minutes, sometimes hours, after the cache is re-enabled. I would appreciate some guidance here. It is kind of urgent as this is a client's site and I can't have it crashing on me completely.
