Undefined index when calling $hrb_options->categories_menu['show']
I get these warnings in the debug.log after every click
[24-Oct-2019 23:47:46 UTC] PHP Notice: Undefined index: show in public_html/
wp-content/themes/hirebee/includes/setup-theme.php on line 206
[24-Oct-2019 23:47:46 UTC] PHP Notice: Undefined index: show in public_html/
wp-content/themes/hirebee/parts/nav-top-bar-secondary.php on line 43
They fill up the debug.log file and both errors include a call to
if ($hrb_options->categories_menu['show'])
Please advise how to prevent the warnings.
