Hi
Sorry to hear you’re having issues with the plugin, we definitely want to try to help out.
What may be happening is that site options table might not be getting cleared correctly when you’ve tried to uninstall, and then reinstalled the plugin. This is an edge-case, but we’ve seen this happen before with various caching plugins that sometimes get in the way of the options table getting cleared.
Another potential issue since you have cleared the cache is if you deleted the plugin manually; the uninstaller would have never been able run and that could be why you’re seeing those errors.
To troubleshoot:
Uninstall the plugin through the WordPress admin area (if applicable).
After the uninstall completes, stay in the admin area and enter
https://yoursite.com/wp-admin/options.php. Here, it will display many options and the values about the site.
Do a quick search (Ctrl-F) for mailchimp-woocommerce-store_id . Confirm that this is either empty or not there at all.
After that’s confirmed, go to Mailchimp and confirm you do not have the website listed in the “Connected Sites” area of Mailchimp.
Re-install the plugin.
Give that a try and let us know if it solved the issue. I look forward to hearing back from you.
