I noticed a small issue with the latest version of the theme. Every post that uses sources or tags has an extra space at the beginning, before the text and even before the side social buttons (see attached image).
All posts with no tags or where the “source” and “via” fields are empty don’t have any problem.
the image you have attached refers to a post where the problem doesn’t show. The issue is only in those articles that use tags or sources (see private field for an example).
I usually use Firefox, but I encounter the same issue on Safari from my iPhone.
