I installed Woo Store Vacation in the latest issue to WP 4.9.1 under Flatsome Child theme. It's Multi-Site installation - and in both languages (both sites) I get a message in a banner saying:
"Woo Store Vacation is enabled but not effective. It requires WooCommerce in order to work."
Is the plugin not compatible with Multi-Site installation?
Because WooCommerce is installed in both sites and works well.
Thanks for your help!
