Hey Mahen,
I’ve had a look at your website – the reason the background slider is not seen is because there is an image set as the default background from the Theme Options panel (“Page Elements” tab, “Website background: image” setting). It was intended in the initial design of the theme, but now I’m thinking that this is not the best configuration. I’ve uploaded a fix into my repository, please download the archive, unzip it, and upload the contained file into the theme folder via ftp (/wp-content/themes/Kabuki). When you refresh the website after that, the background slider should display correctly. Let me know if this corrects the issue!
Sincerely,
Andrew / Satori Studio
