I was looking for adding sharethis.com plug in. Their share buttons are more attractive. But at my admin page can't find a plugin adding option.
Please enable the plugin adding button at my admin page so that I can add the desired plugin.
The link through which I tried- http://support.sharethis.com/customer/portal/articles/446440-wordpress-integration#sthash.cavGckeF.dpbs
The blog I need help with is sumantasaha.com.
