Support » Plugin: HandL UTM Grabber » Cannot modify header information – headers already sent

    Hello!

    I see quite big amount of errors like this:
    [23-Jun-2019 11:19:01] WARNING: [pool www] child 11735 said into stderr: “NOTICE: PHP message: PHP Warning: Cannot modify header information – headers already sent in /var/www/site.com/wp-content/plugins/handl-utm-grabber/handl-utm-grabber.php on line 46”

    I use Ubuntu 18.04 + Nginx + PHP_FPM.

    From my understanding such error may cause issues with UTM tracking.

    I use latest WordPress + latest Handl UTM Grabber.

    Thank you!

    @pavelodintsov, i think the problem is with another plugin. HandL UTM Grabber sets the cookie using the init hook where should be nothing printed to the screen after init. But in your case, it seems like something is being printed and this is most probably due to an error in another plugin.

    Hello!

    Thank you so much for response! I will check other installed plugins.
