php error uninitialized string

[duedl0r]

I get the following error:

Warning: Uninitialized string offset 0 in /home/httpd/vhosts/pilatus-fahrschule.ch/httpdocs/wp-content/themes/lay/customizer/css_output.php on line 1934
Warning: Trying to access array offset on value of type bool in /home/httpd/vhosts/pilatus-fahrschule.ch/httpdocs/wp-content/themes/lay/customizer/css_output_mobile_menu.php on line 337

So I added a check to prevent the message showing up in my page:

wp-content/themes/lay/customizer/css_output.php

public static function hex2rgb( $color ) {
    // this...
    if(empty($color)) {
        return array( 'red' => 0, 'green' => 0, 'blue' => 0 );
    }
    // ... up to here
        
    if ( $color[0] == '#' ) {
        $color = substr( $color, 1 );
    }
   
   ........
}

Maybe this check is not necessary, and there is a configuration error? How can this happen?

I tested this against 6.1.something and the latest version.

Best regards

probably there is a color somewhere that was deleted and doesnt contain anything. will release an update later today that fixes this
