• Look at the file path in the first error. The problem is with your theme. You will need to contact the theme developer. Based on that error, and the last two errors, your theme is out of date and has not been updated for newer versions of WooCommerce and PHP. – Jacob Peattie Commented Dec 31, 2018 at 8:04

Problem lies in your theme. It’s not compatible with PHP 7.2.

In this version the create_function is deprecated and you should use Anonymous Functions instead.

So for example instead of something like this:

$callback = create_function('', 'echo "'.str_replace('"', '\"', $section['desc']).'";');

You should use this:

$callback = function() {
    echo str_replace('"', '\"', $section['desc']);
};
