@eric: It’s strange. I am checking in from same Ipad. This is first time, we see that you are facing issue in iPad. Have you change any setting in your Ipad? Try checking that. Also reset your safari and clear you cache there and check in. If that doesn’t work then try adding following css in “Appearance => Theme Options => Custom CSS” box.
@media only screen
and (min-device-width : 768px)
and (max-device-width : 1024px)
and (orientation : portrait)
and (-webkit-min-device-pixel-ratio: 2) {
.tinynav { display: block; color: #fff; }
}
