I am losing customers and money every day due to this issue. I have tried htaccess rewrites and folder persmission changes. I have tried everything under the sun. Please help me get rid of this issue. Each time my customers click Add To card on the WordProess/WooCommerce site, I get these errors.

I don't care if you give me some HTACCESS file or something that unlocks the folders to the entire planet, please help me fix these errors or I will lose all my customers.
Thanks.
I had a similar problem. For me it was caused by ModSecurity. I fixed it by turnig ModSecurity off. I logged in to cPanel, clicked on "ModSecurity" and turned it off there for my domain. I don't know if it helps on your case, but that's what I did.
You can try adding this in the .htaccess file:
<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>
