[3969120a]

Just deleted 2 plugins (wp smush & another non swift one) and am now getting:

Notice: Uninitialized string offset: 0 in /home/serenitycreams/public_html/wp-content/themes/atelier/swift-framework/core/sf-functions.php on line 1535

here is the code for lines 1531-1551:

/* HEX TO RGB COLOR
================================================== */
if ( ! function_exists( ‘sf_hex2rgb’ ) ) {
function sf_hex2rgb( $colour ) {
if ( $colour[0] == ‘#’ ) {
$colour = substr( $colour, 1 );
}
if ( strlen( $colour ) == 6 ) {
list( $r, $g, $b ) = array( $colour[0] . $colour[1], $colour[2] . $colour[3], $colour[4] . $colour[5] );
} elseif ( strlen( $colour ) == 3 ) {
list( $r, $g, $b ) = array( $colour[0] . $colour[0], $colour[1] . $colour[1], $colour[2] . $colour[2] );
} else {
return false;
}
$r = hexdec( $r );
$g = hexdec( $g );
$b = hexdec( $b );

return array( ‘red’ => $r, ‘green’ => $g, ‘blue’ => $b );
}
}

I commented out line 1535 and the error message is gone.

/*if ( $colour[0] == ‘#’ ) {
$colour = substr( $colour, 1 );
}*/

Is this line of code necessary?

Thanks

Hi,
Please find this code :-

if ( $colour[0] == '#' ) {
$colour = substr( $colour, 1 );
}

With this code:-

if(isset($colour[0])){
if ( $colour[0] == '#' ) {
$colour = substr( $colour, 1 );
}
}

Thanks

Hi Mohammad,

I removed the comment, refreshed the page and the error is gone.

Do we still need to replace with new code?

Thanks
