SDAC Recommends: WordPress Plugin: Update Manager
A number of bugs can easily be solved by making sure you have the latest version of a particular plugin. If you are like most people, you do not have time to go to each and every plugin’s web site and confirm you have the latest version, but the Update Manager plugin will. The plugin is relatively new and somewhat in beta, but it has already saved me countless hours – and hopefully will do the same for you.
