 * Hi [@ondrahatle](https://wordpress.org/support/users/ondrahatle/) , thank you
   for reaching out!
 * The plugin is likely blocking some Facebook scripts and therefore causing the
   error to occur. The best course of action would be to check the [Seraphinite’s documentation](https://www.s-sols.com/docs/wordpress/accelerator/getting-started-accel)
   on how to exclude Facebook scripts from being deferred/blocked by the plugin,
   or reach out to their support team for further assistance.
 * Kind regards,
   Marija
