Forget password not working

You can see if emails are ‘sending’ but you’re just not receiving them with https://www.ads-software.com/plugins/wp-mail-logging/

If not spammed, but logged as sending, it may be a server issue. Try using a different method of email sending with https://www.ads-software.com/plugins/wp-smtp/

You can also combine https://www.ads-software.com/plugins/wp-smtp/ with https://www.mandrill.com/ or https://www.mailgun.com/ for improved deliverability and logging. I recommend this anyway.
