[Plugin: NextGEN Gallery Voting] Image Voting No Longer Works Since Upgrade

I think figured it out. I navigated to the plugin’s folder via FTP client and found the readme file. Along with other details, it mentions this:

= Ok, and how do I make the voting form appear for images? =
For images there’s an extra step. First you still need to enable voing on the specific images you want. Then you need to add a tag to the gallery file of NextGEN. I’m going to use NextGEN version 1.3.6 to as the example, but it should be pretty much the same for all ‘newish’ versions:
Between line 38 and line 50 in /nextgen-gallery/view/gallery.php is the loop that shows each image in a specific gallery. You need to add the following tag anywhere in that loop: <?php echo nggv_imageVoteForm($image->pid); ?>.
That will output the vote form where you put it. Personally I like to place it on a new line after the close <a> tag (new line created 45)

That seemed to fix it for me.
