after trying to turn sharexy off of everything except the blog using the sharexy settings with no luck I created a child theme and added this:

<style type="text/css">
  .sharexyWidgetNoindexUniqueClassName {display:none;}
</style>
 
to the header of all the themes page.php, page-full.php, etc pages and turned it off that way.

I just installed this and I have the same problem. Where is the "widget displaying"? I looked at the plugin and my theme's widgets and I do not understand what you mean?
