I recently updated to PHP 7.4, and I keep getting the following error message for my Theme:
Warning: A non-numeric value encountered in /hermes/bosnacweb04/bosnacweb04ar/b610/myd.photogenica/public_html/photogenicaboothnyc/wp-content/themes/crowd/lib/php/main.php on line 999
The line referenced is:
$submenu_nav_font_size = $navigation_font_size - 2;
Can anyone tell what the non-numeric value is and what the fix might be? I contacted the theme provider and they could not help. It is an outdated theme, but I’m hoping maybe there’s a fix.
