Unable To Change Default Settings

Hello there,
My website is http://www.fantista.com. I am using your Infinite Scroll WordPress plugin. It is working fine but I am not able to change its default settings. I have changed “Loading Message”, “Finished Message” and “Loading Image” but the new settings are not reflecting at my blog.

Please help me to get out of this issue.
Thanks in advance.
