I found my solution!
Note: the solution depends on your theme
In your theme/functions.php, add the following lines:
// WOOCOMMERCE
remove_action( 'woocommerce_before_main_content', 'woocommerce_output_content_wrapper', 10);
remove_action( 'woocommerce_after_main_content', 'woocommerce_output_content_wrapper_end', 10);
add_action('woocommerce_before_main_content', create_function('', 'echo "<div id=\"content-body\">";'), 10);
add_action('woocommerce_after_main_content', create_function('', 'echo "</div>";'), 10);
Instruction #1 and #2 (the ones starting with “remove”) tells your theme to remove woocommerce hooks.
Instruction #3 and #4 (the ones starting with “add”) tells your theme to consider your own rules, rules that you must change to match your theme structure (whether you use div, class, section etc), that you can find in your theme/page.php.
Here, what is specific for my theme is that I use:
"<div id=\"content-body\">" for #3 and"</div>"
but for some people, for instance, the hook can be:
"<section id=\"main\">" for instruction #3, and
the closing instruction #4 will be:
‘Hope that helps anyone.
Peace.
