Here is what the plugin creator says:
"The issue is not with like locker, all like locker does it hide / show the content. If your podpress shortcode is not working within like locker its because podpress does not support nested shortcodes (or shortcodes inside of shortcodes.) Like locker does not modify or filter content at all, so nothing is really being changed only that the content itself is shown or not shown."
If you go to the link I posted above, on my daisypeel.com website, you'll see what I mean. Although the pod press shortcode is inside the like locker shortcode, it's like pod press thinks there is NO shortcode and so puts the player at the end of the content, where the general settings specify. Ten, once liked, the pod press player shows up where the shortcode actually is.
This was an issue before I added the social media plugin, btw.
Thanks again :)
