The placement of the social share buttons (particularly the Facebook button) at the bottom of the article and just above the author's information box is a little problematic.

When a user clicks the Facebook social share button, the author's information box prevents the Facebook dialog box from being seen fully. Consequently, the user cannot make a comment and hit the submit button.

Is there a way to move the social share buttons?

Hello csmith,

Depending on your template you need to either edit your template's item.php or override if it doesn't exist. The code is well commented and you won't face any issues moving that block.

More on overriding can be found here: getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates
