The script is creating a conflict with other document.ready functions in jQuery since version 184.108.40.206. The version 220.127.116.11 works okay. I have not been able to locate the exact code segment which creates the issue.
The issue can be hopefully recreated by addition a document.ready function in to the header.php in WP
example page http://amazinglanka.com/wp/demali-ella/ but this is running down graded plugin ver 18.104.22.168
