` tags. It may break your theme. There is also an option named "Codeless" which attempts to place the container code correctly without additional theme tweaks. It may or may not work, this is an experimental feature, use it accordingly. = Why can't this plugin insert the container snippet after the opening body tag automatically? = Currently WordPress has two 'commands' or 'hooks' that a programmer can use: one for the `` section and one for the bottom of ``. There is no way to inject any content after the opening `` tag without manually editing your template files. Fortunately some theme authors already resolved this so in some cases you do not need to edit your template. I suggest that try the Custom placement (easiest) and use Google Tag Assistant Chrome browser extension to check whether the container code is placed as expected. If it shows an error, go ahead and edit your theme manually. = Facebook like/share/send button events do not fire for me, why? = It is a Facebook limitation. Click event tracking is only available for html5/xfbml buttons. If you or your social plugin inserts the Facebook buttons using IFRAMEs (like Sociable), it is not possible to track likes. == Screenshots == 1. Admin panel 2. Basic settings 3. Events 4.
