Yes, by using Appearance > Theme Options
The Customize feature still doesn’t work for me.
I’m not really sure how I fixed the issue.
These are the steps I took that I believe might have led to the Bootstrap Slider to work properly (including the return of the arrows (< >) in each slide:
– Appearance > Theme Options > Bootstrap Slider > Slides > #5 (the one that I had the issue with the Header 1 superimposed on it)
– Deleted the button code and re-entered it
– Save Changes
