WordPress Comments / Woocommerce

Hi,

When I activate the WordPress Comments integration option a tickbox appears under the reviews tab within my Woocommerce single product items. However, this box is not allowing itself to be ticked and therefore reviews are not able to be left.

If the checkbox is left blank then a warning is given asking for it to be checked but this is unable to be done! I have deactivated all other plugins and this issue still persists.

Any help and advice on this would be great.
