Hello,

First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :-).

The black background is only added when the dark mode is enabled. Please make sure that you haven’t enabled it from Theme Settings >> Styles and colors.

If the issue still remains then provide the URL of the website to check it myself and help you out accordingly.

Regard’s.
Xtemos Studio.
