Have both ATUM Product Levels and ATUM Inventory Management for WooCommerce, and after last Woocommerce Update I had to deactivate ATUM Product Levels, because when active it make all the products pages crash (can't open front end and getting an error)
I disabled and reenabled one by one all plugins and found out it is ATUM Product Levels the problem. All plugins are now updated
How can I fix this? Thank you!
