Just wondering if anyone else has had this issue, our site is currently running 4.0.2 albeit an old version of WooCommerce, however, there was a security update over the weekend to remove Paypal standard from WooCommerce which forces an update to 4.0.4.
The site has tried to do this but it didn’t successfully complete the update and in turn break the site with the following error:
PHP Fatal error: Uncaught Error: Call to undefined function is_woocommerce()
To fix the issue we manually download 4.0.4 and over write the files, however, within a couple of hours we have the same issue again.
WordPress version: 5.7.5
WooCommerce Version: 4.0.4
