Can't find slider options

Hi @yondoloki,

I hope you are well today and thank you for your question.

On checking the theme slider option “Check if you want to enable slider”, you will get two options “Slider Category” and “Number of slide items” which is displaying in your this shared screenshot http://www.yondoloki.dk/wp-content/uploads/2015/10/Untitled-1.jpg

You are getting only one default category “Uncategorized” in the drop down because i think you have not created any custom category on your site and assign it to posts so please do this as described on the following pages.
