hello. I soved this issue by adding a line with WC()->init(); in the start of function load_scripts() in file class-wc-frontend-scripts.php (around line 55)
Hello. I had the same problem here. Solved it by replacing every instance of string ‘wp-content’ with my content folder name which was ‘stuff’. I had changed my content folder when installing ithemes better security plugin and that is what caused the issue. The wp-content string though should be dynamically fetched by the pipe plugin!
