Hello, thanks for analysis and advice. I went according to the instructions turned off Root Folder BulletProof Mode Deactivate wp-admin Folder BulletProof Mode and custom code I have two codes. One which authorizes http head and the other to permit the pdf catalog in iframe plugin pdf viewer – jupdf pdf viewer. Even after deactivation does not add to the cart and the woocommerce ajax obviously still something blocks. Here is the content of my custom code:
These custom codes allow HTTP head and iframe pdf viewer. Nothing more. WP admin custom note is empty. I use the free version of BPS. The problem persists, woocommerce ajax is enabled in the settings woocommerce
