I have viewed your gallery in Chrome 30 and Mobile Safari on an iPod Touch 4 and your gallery displays and functions correctly in both browsers.
I have also taken a look at your gallery files on your web server and everything looks to be in order.
If you have made any changes to your gallery recently, try clearing your browser's cache before reloading your gallery to ensure that your browser is fetching and using the most recent versions of your gallery files from your web server.
Also, if your mobile devices are using a 3G connection rather than wi-fi, please see this FAQ:
Why can't I view my gallery on a 3G mobile connection?
If you think that this might be a contributing factor, a possible solution would be to create an .htaccess file containing the following code and upload it to your website's root directory. (Please note that this requires an Apache web server.)
Header set Cache-Control "no-transform"
This should prevent content modification on your site when visitors view your galleries over a 3G connection.
You could also contact your 3G provider to see if it is possible for content modification to be turned off on your account (although this will help only when you view other people's galleries and will not solve the problem of other people viewing your own galleries over their own 3G connections, which the solution above tackles).
