I have installed (and then reinstalled after this happened the first time) the latest version of your plug in and opted to only display the widget in the sidebar. Where the widget should be displayed is the message "Not Found (404)
The requested URL /bbb/wp-content/plugins/pinterest-" The first time, I tried to find the source of the error in the plug in files but could not - I only have a rudimentary understanding of html/css.
I was wondering why this happened/how I might be able to fix it.
I understand that offering support must be quite time consuming, but I have tried a couple of other plug ins and yours is the one I really want to use! I really appreciate your time :)
