I have in the past day upgraded WordPress and the Share/Save Plugin since doing this the share/save button has disappeared from all posts with the exception of one and it appears partially behind an image in the excerpt above the image where it was previously was absent.
Prior to the latest upgrade none of these problems existed. I'm using the Organic Portfolio Theme for this website.
I checked the plugin settings and there were no changes there. When I unchecked "display at bottom of posts on front page" this resolved the issue where the share/save button was hiding behind the image but the issue of the share/save button disappearing on the posts is still present.
