Did your Google Analytics code survive your latest upgrade? Is it still there when you changed your skin? No worries anymore. This plugin will inject the Google Analytics code into every page in your blog, even in the Admin section. You will need to copy/paste the pageTracker code, formerly known as _uacct, to the setting of the plugin.
Important note: in most cases, since the Custom javascript section field is available, you won't need a plugin to use Google Analytics with your b2evolution blogs. For more information, please go to this page: Skin and Style Panel
