Hi,
I am expert of Woocommerce. Theme got outdated. I suspect it is a custom theme that's why it did not got updated and go broken on Woocommerce update.
The other warning message is from woocommerce as updated version needs to make some changes to bring database to latest version. This can also break any other plugins those are not updated and are dependent upon woocommerce database structure. I will take care of this as well.
I will fix it in one day. I will need wp-admin and FTP logins.
If you have any questions, feel free to ask.
Regards,
Kamran
