I am experiencing the same problem. Apparently it is related to “touch events” and only occurs on touch enabled laptops and google chrome (not having the issue in IE)
Do you have a touch screen laptop? Try tapping the link instead of clicking.. for me that works, but i don’t expect my users to do this so until there is a fix unfortunately I am going to switch from this theme to another.
I deleted that snippet of code you mentioned and still getting the error however that may be because of the caching plugin my host forces me to use. I’ll try to check back later. So far no reader has complained.
