 * I’ve been seeing this error appearing in the javascript console in a form that
   I’m working on. The form has sliders, which continue to work, and the form functions
   properly so it isn’t a fatal problem, but it maybe something that can be resolved.
 * Uncaught TypeError: Cannot read property ‘slides’ of undefined
    at HTMLDivElement.

 * ok, thanks for this report. Any chance you can run your setup with WP_DEBUG enabled
   so that the plugin loads the uncompressed cf7-grid-layout-public.js script? This
   would make it easier to debug and step through to see why the object isn’t accessible
