The Boom Bar plugin has been deprecated as the developers no longer support it. If your site still has this feature, please contact support@fivemoretalents.com to let us know, as this plugin will need to be removed and replaced with a different plugin called My Sticky Bar.
The instructions to configure a Sticky Bar (Once the plugin is installed) are attached. Please email support@fivemoretalents.com with any questions or if you need further help.
Thank you!
