Hello Tony Thanks!
So what happened was is that I was trying to edit the cart page and looked at a video on YouTube (attached on private area)
Then I added the following plugins
1) WooCommerce blocks
2) Elementor Header, footer, and block templates
3) Essentials addons for Elementor
4) WooLentor
I have deleted all these plugins since.
After I tried to change back the old cart was back but the format is all messed up.
Please let me know if that can solve this issue or else I will provide the login details.
Thanks!
