I've been using this plugin for the past 2 weeks since I moved to WordPress. I'm not sure if it's a plugin issue or conflict but it only works randomly.
I have a Lightbox plugin too so my images enlarge in such a way rather than opening to just the photo and the user having to go back (some non-techy people don't know how to go back!)
I've tried disabling the lighbox plugin but sometimes it just add a # to the address bar and nothing pops up. Sometimes it does. It's been the same whether or not the Lightbox plugin is activated or not.
I love this plugin [when it was working] and it definitely increased people pinning on my site so I'd love to work through a way to get it back up and running again, if possible?
