I am running multiple sites based on wordpress on shared webhost. Recently I got hacked and warned by my webhost bcos one of my WP site running old version of WP had been hacked and spam sent using that site.
The problem is you have to update each WP install manually. Sometimes, there are sites which are less important and you tend to forget to update them. Is there any way/plugin that will allow updating multiple installs of WP without visiting each WP site and updating manually?
