We are using 1.3.6. Disabling the plugin fixes the problem. Please help. * Warning: Invalid argument supplied for foreach() in /home/content/p3pnexwpnas08_data03/ 30/2845930/html/wp-content/plugins/woocommerce-mailchimp/classes/class-ss-wc- integration-mailchimp.php on line 358 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/p3pnexwpnas08_data03/30/2845930/html/wp-content/plugins/woocommerce- mailchimp/classes/class-ss-wc-integration-mailchimp.php:358) in/home/content/ p3pnexwpnas08_data03/30/2845930/html/wp-admin/post.php on line 242 * Warning: Cannot modify header information – headers already sent by (output started at /home/content/p3pnexwpnas08_data03/30/2845930/html/wp-content/plugins/woocommerce- mailchimp/classes/class-ss-wc-integration-mailchimp.php:358) in/home/content/ p3pnexwpnas08_data03/30/2845930/html/wp-includes/pluggable.php on line 1207 * [https://wordpress.org/plugins/woocommerce-mailchimp/](https://wordpress.org/plugins/woocommerce-mailchimp/) Viewing 8 replies - 1 through 8 (of 8 total) * [hxxrmonkey](https://wordpress.org/support/users/hxxrmonkey/) * (@hxxrmonkey) * [10 years, 6 months ago](https://wordpress.org/support/topic/error-661/#post-6653779) * I’m having the same problem, the first error on line 358, we are using the latest version. Also tried a new API key and didn’t fix the problem. * Plugin Author [Adam Anderly](https://wordpress.org/support/users/anderly/) * (@anderly) * [10 years, 5 months ago](https://wordpress.org/support/topic/error-661/#post-6653790) * Would you both mind contacting me via my blog at [http://anderly.com/contact](http://anderly.com/contact) and sending me a new test API key for your MailChimp accounts and I can test connecting locally on my machine? Please send me a test API key (not your current API key) – that way you can delete it after I’m done testing. * [brad hogan](https://wordpress.org/support/users/bradley2083/) * (@bradley2083) * [10 years, 5 months ago](https://wordpress.org/support/topic/error-661/#post-6653793) * Did you find any solution to this issue? I am experiencing a similar error.

She’s just turned it off for now. * Plugin Author [Adam Anderly](https://wordpress.org/support/users/anderly/) * (@anderly) * [10 years, 5 months ago](https://wordpress.org/support/topic/error-661/#post-6653795) * All, I just tested the current plugin version (1.3.6) on a fresh install of WordPress 4.4 with the latest version of WooCommerce (2.4.12) and it appears to be working fine. If you can, please send me your install details here: [http://anderly.com/contact](http://anderly.com/contact) * Please include WordPress version, WooCommerce Version, Plugin Version, PHP Version and the WebHost you’re on. * I’d love to help you all get it working if we can. * Cheers, * Adam * Plugin Author [Adam Anderly](https://wordpress.org/support/users/anderly/) * (@anderly) * [9 years, 8 months ago](https://wordpress.org/support/topic/error-661/#post-8206855) * Just wanted to let you all know that we recently released version 2.0 of this plugin.
