Error Log – Missing Argument

I am getting a message in the Error Log that starts out with:

Missing argument 2 for WINP_Execute_Snippet::executePostSnippets(), called in .../wp-includes/class-wp-hook.php on line 286 and defined in .../wp-content/plugins/insert-php/includes/class.execute.snippet.php on line 60

I am only using one PHP snippet. It’s very simple:

if(isset($_GET['name'])){
	    echo do_shortcode('[wbcr_text_snippet id="15443"]');
	} else { echo do_shortcode('[wbcr_text_snippet id="15442"]'); }	

The other two snippets are text snippets.

Can you tell why I would be getting this error in the Error Log? The pages work fine.

Thank You!
