wordpress password reset link not work
<p>on my WordPress website when i reset my account password by entering my email and pressing reset on the lost-password page, i get the confirmation to check my email for confirmation link, 
<a href="http://i.stack.imgur.com/I49oc.png" rel="nofollow">enter image description here</a>
however i never get the email, the email doesn't reach the inbox neither the spam folder, in other words the email does not go.
Why could that be?
Emails from other forms from the website work, contact, registration, product purchase.
I am using woo-commerce on the website.
How can i overcome this?</p>
