1) I’m using the Mantra theme and with the presentation page it is stuck on a infinite loading when viewed on the iPhone. The slider works, but the bottom half has the loading circle and never stops. It works just fine on the iPad and the computer. any ideas?

2) Also, I have it where on menu bar the tabs that have a sub category; the parent (or tab) doesn’t have a url. Which is fine. but when the menu shrinks down to the iPhone it turns into a drop down menu and the parents (tabs) have a url and say that the page wasn’t found. I don’t know how to stop you from clicking the parents (tabs). Any help?
