Writing appearing underneath all photos!

I updated my plugin yesterday and immediately got an error message under every picture that said: Warning: in_array() expects parameter 2 to be array, string given in/home1/myname/public_html/wp-content/plugins/jquery-pin-it-button-for-images/includes/public/class-jpibfi-client.php on line 92

and then it repeated for line 93

I reinstalled and that message has now disappeared, but has been replaced with a portion of the headline from each post underneath all images.

Have cleared cache and that isn’t helping.

Need this back up and running asap! And advice? Thanks!
