@kinney0201 You are posting a reply to a *resolved* topic. It’s best to start a new topic with your own question.
Meanwhile, I think the “instructions” you are referring to are comments within the javascript file that comes with the plugin. That comment goes on to say that it’s overriding the setting, regardless of what you did previously.
The installation instructions do not require you to change anything; you simply activate the plugin.
It works for themes with a background image set on the HTML ‘body’ element; if your background image is created in any other way, this plugin will not work.
Please start a new, separate conversation thread if you have follow-up questions. Thanks!
