I desactivate some of the plugins to see why something was making conflict on the site. (Media Gallery was not working) and suddenly Im getting this error:

This is more of a Wordpress issue than an issue with Woocommerce. Something is writing out to the browser before the php is executed. Could be something in your theme or something in a plugin. It wouldn't take long to fix but it will take some detective work.
I have 10 years development experience with Wordpress. I can definitely fix this for you quickly.
Thanks,
