Thank you Sayantan, you are great. Now my site sidebar issue has been solved . It has been solved Under Back-end -> Site Optimization.
But there is one problem now . If you watch the home page then you can see the home page main content widget like the horizontal slider border has been detached from the right hand side. But except this home page all the pages are OK. I am using the custom layout for home page and default template for all other pages. Please give any solution.
My site URL is http://coralindia.com/dev/eshop/
Thank you again,
