I have a website. HauteButch.com based on wordpress platform. It seems slow to me and hence I enabled wp-super cache on it. The website seems to have improvement now but when I share link of any page of my site on facebook, the thumbnail do not show up. Can you help what can be done so that thumbnails will be shown as well? (Note: When I disable caching thumbnails Work normally. ) Also what else can be done to speed up the site?
Thanks in Advance.
