@ryanhungate Hello!
few things changed… we moved installation of the WordPress & WooCommerce from subdomain to the main domain. Page is NOT multi-site. Just regular single WP installation running WordPress with DIVI theme.
Server hosting is FastPanel interface running Nginx & Apache2.
I tried reinstalling the plugin and going through activation again and…
Firefox, nor Chrome browser, no longer logs any cross-origin error when hitting the CONNECT ACCOUNT button. I can see it sending POST request to url:
/wp-admin/admin-ajax.php?_fs_blog_admin=true
with content:
action=mailchimp_woocommerce_oauth_start
Unfortunattely response is 400 Bad request.
—————————
I tried doing fresh install of WP & DIVI & WooCommerce & Mailchimp for WooCommerce on the same hosting (no other plugins etc. installed) and authentication popup window for Mailchimp will show.
I also noticed (in this fresh setup) that during the load of the page with configuration of the plugin.
/wp-admin/admin.php?page=mailchimp-woocommerce
I see AJAX loader animation at the bottom of the page content and I cannot see that on the main domain of my client’s page.
Not sure if all of this will help you any…
