I've noticed if you have an outdated version of WP along with a outdated WP woocommerce theme but you update the woocommerce plugin to the recent version I've noticed it breaks the site. (who'd have thought?)
I'm wondering if you are able to just find an older version of woocommerce and this would perhaps fix the issue at hand?
It's not my site but the person who owns the site isn't wp savvy and is adamant not to update the theme and version of wordpress because "it's been fine the way it is"
Any help or recommendations would be great.
Cheers,
Dev
