I installed this plugin to try it out but found it didn't serve my needs and didn't work (pin buttons didn't follow the setting to pin using the page title but rather used the image descriptions).
I disabled and deleted this plugin using the plugin page on my WordPress site, but I still get pin buttons on my images. I'm getting them all across my site. I had set the plugin to only show them on single posts but I get them all over. I've tried deleting caches, trying different cache plugins, re-installing and re-uninstalling the plugin. All failed. I still get pinterest buttons all over my site.
