The issue is “A PHP session was created by a session_start() function call. This interferes with REST API and loopback requests. The session should be closed by session_write_close() before making any HTTP requests.”

I will be grateful.

Thanks

I keep getting a PHP error:

I’ve noticed a php warning happening regardless if I’m using php 7.3 or 8.4

“Invalid characters passed for attempted conversion, these have been ignored”

I got the alert in Query Monitor plugin which monitors for any backend slow downs and errors. I’m not seeing the error on all my sites though. Can you please take a look what’s up?

Could you tell me how to fix this?

Here’s the warning I am seeing:

Warning: Cannot modify header information - headers already sent by (output started at /srv/users/ecom/apps/sitename/public/wp-content/plugins/kount-fraud-prevention/constants/index.php:372) in /srv/users/ecom/apps/sitename/public/wp-includes/functions.php on line 6878

No other notice/errors – but – it does seem to take the site down.

includes/classes/Authenticator/Login.php:549
if ( 'backup_codes' !== $provider && SettingsPage::are_backup_codes_enabled( $user->roles[0] ) && isset( $codes_remaining ) && $codes_remaining > 0 ) {

includes/classes/Admin/Controllers/class-settings.php:177

if ( null === $role ) {
    $role = $user->roles[0];
}

I temporarily fixed the problem at my site by replacing $user->roles[0] into array_pop($user->roles) but that doesn’t solve the problem globally. I think you should add an util that will get the role regardless of indexes
