Thanks for bringing this my attention. We did multiple rounds of testing on older version of iPhone and latest iPad model and things looked fine. I did notice some issues with twitter widget on iPad on some pages (only in Safari and this issue is reported for several themes) and I am looking into the issue. Since I do not see the twitter widget on your site, I guess this should not be the issue. While I have a look at this issue, can you check if it loads fine on Chrome browser in iPhone 5 ? Thanks
