I have the newest vs of Shareaholic & I found out that a grey bar/box appears and covers the footer of my website when viewed with a Safari browser on an iPhone (I haven't tested on other mobile/tablet devices). It starts to appear when you rotate the device from vertical to horizontal, then back, & also when you zoom in and out of a page.
I have many plugins but I believe this happens when the Buddypress plugin is activated. I also use the shortcode to manually place it in the loop & I have the footer removed from posts only.
My website is http://streetstyleedition.com/
Thanks in advance for the help!
