How to combine text with image pinned

I’m NOT a coder, but after reading your help stuff I decided to look at the functions.php file. Sure enough my predecessor added this code:

function gh_add_pinterest_via_shortcode( $content ) {
	 if ( /*current_user_can( 'manage_options' ) &&*/ is_single() || is_home() ) {
		$pin_content = str_replace("'", " ", trim( strip_shortcodes( rtrim(strip_tags( get_the_content() ), "Daily Quote") )));
		$content = $content . do_shortcode("[pinit description='$pin_content']") ;
 	}
	return $content;
}
add_filter( 'the_content', 'gh_add_pinterest_via_shortcode');

So any idea why that would’ve stopped working? It’s in a customized child theme of 2010 if that tells you anything. Thanks.

NOTE: I removed a backtick from that code between the quote marks so it would all display as code.

thanks for responding. I found the fellow who did the work initially and he’s going to fix it for us. AND I determined that we did indeed update the plug-in on Friday which is what caused this.

General has Image is pre-selected checked and Save your settings when uninstalling this plugin. Useful when upgrading or re-installing is also checked.

And Post Visibility only has this checked: Below Content and nothing else.
