Hi
Either its one of your plugin or the theme itself is trying to show the google content on the pop up.
Try replacing the codes of text widget by this once:
<div style="text-align:center; cursor:pointer;" onclick="window.location='https://drive.google.com/file/d/0B415wmSiIEcKNEpvam1DOGtvbEE/edit?usp=sharing'">
<img src="https://www.telliconewvillagers.com/wp-content/uploads/2014/02/Newsletter-Scan.jpg ">
</div>
Let me know how it goes.
Thanks
