Great Plugin But Has Issues With Webmasters Tools

It’s a great plugin and has done what I exactly wanted it to do for me. However, after installing this plugin, I received a warning from Google Webmasters Tools telling me that a page was not found (https://exampl.com/pt_view/grid-id-8c782c1b96/). I’d appreciate it if you can kindly let me know how to get rid of this error.
