cant send an email on cakephp3 - php

Question

I can't get cakephp3 to send emails. In cakephp2 I could do this no problem. I am using the latest WAMP, and cakephp3.3 on Windows 7. I tried to follow the directions but it looks like I am getting something basic wrong. Do I also need to configure Wamp as I checked the php.ini-development file but there is no smtp entry to change

Sending Mail using CakePHP 3.0

Answer 1

I had the same issue when making an HTTPS request using Cake\Network\Http\Client
To resolve the problem, I had to download "cacert.pem" file from https://curl.se/ca/cacert.pem
And then I updated php.ini by adding the following line:
openssl.cafile = <PATH_TO_CACERT_PEM>/cacert.pem
Don't forget to restart the web-server.
If the above thing doesn't make it work, try to update the OpenSSL library installed on your system.
I really hope this works for you too.
