Error on last update

Hi, first of all thanks for your plugin!

On this last update (4.0) I got “the email” that wordpress found an error with one of my plugins, Post Snippets (free).

With the following error details:

E_ERROR en la línea 44 del archivo /home/****/****.com/wp-content/plugins/post-snippets/views/jquery_ui_dialog_footer.php. Mensaje de error: Uncaught Error: Call to undefined method PostSnippets\Shortcode::filterVars() in /home/****/****.com/wp-content/plugins/post-snippets/views/jquery_ui_dialog_footer.php:44

#6 /home/****/****.com/wp-admin/update.php(53): iframe_footer()
#7 {main}
  thrown

I checked the website and used the plugin on a post and everything seems fine, no issues found, but the fatal error message still worries me.

Should I roll back as you suggest?: (Thank you to updating Post Snippets v 4.0, we have recoded the entire plugin please check your all snippets if there is any issue you can download the previous version from here).

Thanks for your help!
Regards,
