The redirect may be caused by WPtouch Pro trying to break out of frames. You can try yourself:
Via FTP, open /wptouch-pro-3/themes/foundation/modules/base/base.js and find:
// Try to get out of frames!
function wptouchFdnEscFrames() {
if ( window.top != window.self ) {
window.top.location = self.location.href
}
}
and change it to:
// Try to get out of frames!
//function wptouchFdnEscFrames() {
// if ( window.top != window.self ) {
// window.top.location = self.location.href
// }
//}
and see if that helps resolve the issue.
