Thank you for prompt response.
The error happens actually on any third-party theme. I was in contact with Astra and the first thing they asked me to do was to check different themes. Everywhere the same error happened with get_cart_contents_total() on null … How this could be resolved in this case? This becomes somehow critical for us.
Exactly the same issue. The moment I deactivate woocommerce adding pages works. Once reactivate critical error shows up.
