Hi,
I’m getting warning messages on a site with EE3 running PHP7+
Warning: session_start(): Cannot start session when headers already sent in /var/sites/w/xxxxxxxxxxxx.co.uk/public_html/xxxx/wp-content/plugins/espresso-multiple/espresso-multi-registration.php on line 77
Warning: session_start(): Cannot start session when headers already sent in /var/sites/w/xxxxxxxxxxxx.co.uk/public_html/xxxx/wp-content/plugins/event-espresso/espresso.php on line 80
1) Do these warning mean the EE3 plugin will not work properly?
2) How do i resolve these warnings?
Thanks,
Elaine

Hi Elaine,
I’ll answer your questions below:
1) Do these warning mean the EE3 plugin will not work properly?
No, the EE3 plugin should still work properly.
2) How do i resolve these warnings?
It’s not clear why you’re seeing the warnings in the first place, so this will usually require some troubleshooting. It is usually because there are spaces, new lines, or other stuff before an opening <?php tag or after a closing ?> tag, typically in the wp-config.php or in the theme’s functions.php file if that file has been edited. This could be from any other file that’s been edited. So if any files have been edited you can check those first.
You can follow this guide to further troubleshoot this:
