Still works for PHP 8.1 and WP 6.1 – Minor fix

Hi.
The theme works in WordPress 6.1 and PHP 8+.
The only thing which needs change is the function “tenderSpring_custom_css” which throws a PHP Warning.
Change it to the following.

/**
 * Custom CSS support
 */
function tenderSpring_custom_css() {
   $options = get_option( 'tenderSpring_theme_options' );
	if ( (is_array( $options ) ) && ( array_key_exists( 'custom_css', $options ) ) ) {
		$tenderSpring_customcss = $options['custom_css'];
		if ( $tenderSpring_customcss ) {
			echo "<style type='text/css'>";
			echo $tenderSpring_customcss;
			echo '</style>';
		}
	}
}
