WordPress HTTP Error 500 via password recovery

Posted on August 22, 2016

I was following this guide and when I click on ‘Forgot password’ and enter my email for a recovery link, it brings me to a page that says, The MYSITE.com page isn’t working MYSITE.com is currently unable to handle this request. HTTP ERROR 500

Here is my nginx/error.log I have sendmail installed with default configuration.
