Sayontan Sinha on "[Plugin: Photonic Gallery for Flickr, Picasa, SmugMug, 500px, Zenfolio and Instagram] Photonic_SmugMug_Processor.php"

I get the following error displayed on my website's photo albums:

Fatal error: Cannot use object of type WP_Error as array in /home/xxxxxx/xxxxxx/wp-content/plugins/photonic/extensions/Photonic_SmugMug_Processor.php on line 166

Any idea how to work around this?
I've got all of my plugins updated.
It's definitely coming from this plugin "Photonic Gallery for Flickr, Picasa, SmugMug, 500px, Zenfolio and Instagram"

Any help would be greatly appreciated. Also, I'm sorry, but my skill with coding is practically nonexistent, so I guess I'm asking for the simplest language in understanding how to go forward with this problem.

THANK YOU!
