Error with Plugin

I have encountered an error when using the plugin. I can see the profile picture upload section on the account page but when I upload a photo I get the following error:

Warning: mime_content_type(): Empty filename or path in /home/*site name*/public_html/wp-content/plugins/woo-custom-profile-picture/woocommerce-custom-profile-picture.php on line 65

Can I do anything to fix this?

Thanks,

Joe
