Hello,
Again the problem with plugin was caused by wrong permissions. I’ve set the correct ones.
Do you upload files via FTP using root user? In this case permissions of folder are set to 700 instead of 755.
I’ve renamed folders and files in your child theme “woocommerce” folder that were removed in the theme package. Now “Proceed to Checkout” button is shown on Cart page. Clear browser cache and check.
Regards,
Eva Kemp.
