I’m not really sure how I fixed it.
These are the steps I took that led Header 1 to appear again on my Home Page and for the Bootstrap Slider to work properly (including the return of the arrows (< >) in each slide:
– Appearance > Theme Options > Header > Menu
– Choose menu item hover effect: Smooth
– Appearance > Theme Options > Bootstrap Slider > Slides > #5 (the one that I had the issue with)
– Deleted the button code and re-entered it
– Save Changes
After I did the above, Header 1 worked as it did before.
