You need to install WooCommerce first to use Add-on WooCommerce MailPoet 3

Hello,

After upgrading to the latest WooCommerce version (Version 3.5.1), I have the following error message, when activating the plugin again:
Hold on a minute. You need to install WooCommerce first to use Add-on WooCommerce MailPoet 3 .

WooCommerce is installed and activated (as you can see from the web site).
Add-on WooCommerce – MailPoet 3 plugin used to work ok before the WooCommerce upgrade.

Note that I am using the OceanWp theme (with a child theme) and a few others plugins have similar issues (Woocommerce Wishlist, WooCommerce PDF Invoices & Packing Slips, Cross Sell Products Display).

The page I need help with: [log in to see the link]
