Keep Track of When WordPress Plugins are Activated and Deactivated
Plugin Activation Date is a new plugin that helps you to keep track of all of your plugins. It adds a new column to the plugins management page that shows you when each and every one of your plugins was last enabled or disabled. This can be very valuable information when you are debugging a WordPress install.
When troubleshooting a site with 30 or more plugins you may find that knowing the plugin activation dates can help you to discover the source of the problem and retrace your steps. Download it for free from the WordPress plugin repository.
