Sorry to bother you with this. I found your plugin and installed it. I downloaded version 2.0. I believe I've done everything correctly installing it. However, when I place an image on my post page it doesn't activate Simple Lightbox. There are no other plugins installed for this theme. You can see the page here: http://www.watkinswebdev.com/albumdesign/2013/09/favorite-album-project/
I've looked at the code and it does seem to be calling all your stuff, but no lightbox. Thanks for any help.
