[Fstorm]

I recently updated my site. Before I did'nt start constructing, so google's cache showed only the index of the files in the public_html folder
Now after I uploaded my all pages, google does not show any 'cached' link nor is any matter of my site is shown if I search in google. Can anyone please help me?
Thanks
