Touch screen not working on one site.

johannabasford.com. Coloring gallery on upper left.

IPad Air2 IOS 8.4

For the past couple of weeks I haven't been able to change the "like" to "liked" on the small pictures. I can still enlarge them. I seem to be the only person that votes on this site having a problem.

Make that upper right corner. Can't get the cursor to go up to change that. Seems to be my only problem.

thanks in advance!
