The error that I have is a very common error. Yet I saw that the error message is different per person. The message I am getting is:

array(4) { [“type”]=> int(2) [“message”]=> string(171) “Cannot modify header information – headers already sent by (output started at /home/radioprog/domains/radioprogrammabank.nl/public_html/wp/wp-includes/formatting.php:5688)” [“file”]=> string(145) “/home/radioprog/domains/radioprogrammabank.nl/public_html/wp/wp-content/plugins/insert-php-code-snippet/shortcode-handler.php(65) : eval()’d code” [“line”]=> int(61) }

When I change themes (twenty nineteen), the error does not go away. It simply changes to:

array(4) { [“type”]=> int(2) [“message”]=> string(175) “Cannot modify header information – headers already sent by (output started at /home/radioprog/domains/radioprogrammabank.nl/public_html/wp/wp-includes/class.wp-styles.php:287)” [“file”]=> string(145) “/home/radioprog/domains/radioprogrammabank.nl/public_html/wp/wp-content/plugins/insert-php-code-snippet/shortcode-handler.php(65) : eval()’d code” [“line”]=> int(61) } upload is gelukt

I tried to go to the formatting.php and changing what was wrong, but it did not solve my problems.

I have a header() function that needs to redirect people to another page. When I var_dump it. The first error is shown. I want the error to go away so that I can redirect visitors to a different page using the header() function

shortcode-handler.php (line 55 – 75):

    $content_to_eval='?>'.$content_to_eval;
}

/***** to handle old codes : end *****/

    if(substr(trim($content_to_eval), 0,5)=='<?php')
        $content_to_eval='?>'.$content_to_eval;
}

                        eval($content_to_eval);
                        $xyz_em_content = ob_get_contents();
