Homepage header slider is a built-in function in all of our themes, both non premium and premium. If you are using this feature, I’d strongly suggest to disable other external / third-party slider plugins as it may overlap with the built-in one.
By default, the homepage header slider will show the latest 5 posts from your blog. It only shows posts WITH featured image assigned to the post, so please make sure that your posts have featured image assigned to them.
How to edit the slider
Go to APPEARANCE >> CUSTOMIZE >> SLIDER SETTINGS.
You can choose the slider style, change the box background color, choose to show only specific blog category, and number of slides.
You can also choose the slider to show static images, instead of showing your latest blog posts. On the “Slider Images” option, opt for custom images and upload your image(s).
