jquery mobile add large space below footer.

jquery mobile add large space below footer.

Hello all. First time trying query mobile, using it on my wp theme. 
After enabling jquery mobile i now have a large blank space with the text "loading" below the footer.

I have already google for this issue and the solution of adding 
data-position="fixed" data-fullscreen="true"
to the header and footer did not work.
the site is at http://agileart.us/
Could i please have some advice on  how to solve this?

addendum:
it seems to me that possibly one of the issues is that jqm is preventing  this


Failed to load resource: net::ERR_FAILED
XHR failed loading: GET "chrome-extension://boadgeojelhgndaghljhdicfkmllpafd/cast_sender.js".


Thank you 
DLM
