Hello all

I have this message when I want to syncronize vtiger and mailchimp
Warning: Invalid argument supplied for foreach() in C:\Program Files\vtigercrm-5.2.1\apache\htdocs\vtigerCRM\modules\Mailchimp\SyncWithMailChimpUtils.php on line 479

Anyone have an issue for that?

foreach($batch as $member){
$string_email .= '"'.$member['EMAIL'].'",';
$list_email[] = $member['EMAIL'];
}

Hi Seb974, Seems like no one has seen this error. Did you find any solution?

Did you add your contacts to your Mailchimp campaign in Vtiger?
I had the same problem until I added my contacts to the Campaign

Confirming that this still fixes this issue in 1.1 for 5.3. You have to have contacts in your *MailChimp* campaign. I'd added my contacts to the core vTiger campaigns.
