Eliminating top row on my website

The persistent admin bar for logged-out users is likely due to the settings of the BuddyPress plugin you’re using.

Kindly go to SETTINGS => BUDDYPRESS => OPTIONS, and under MAIN SETTINGS => TOOLBAR, check off “Show the Toolbar for logged out users”

Thank you. Can I eliminate the black bar?

That black bar you see actually is from your theme!

To populate that “Toolbar” with content (see example below), go to:

APPEARANCE => CUSTOMIZE => TOOLBAR SETTINGS

To change the background color, go to:

APPEARANCE => CUSTOMIZE => COLORS and change the “Toolbar Color”.

To completely hide this top bar, add the following custom CSS code in APPEARANCE => CUSTOMIZE => ADDITIONAL CSS:

#toolbar {
display: none;
}
