Dear Femi,
Thanks for your advice. I turned off every non-essential plugin. I came to the conclusion that I was able to get the wright checkout process. I figured out it is because of Elementor Pro, but I find this very odd because I have used this plugin on a lot of other woocommerce websites and they all work absolutely fine.
Is there anything I can do to make this work? Please help! (I already tried installing elementor pro again)
Thanks in advance!
