SSL Security Issue When Trying to Send Test Email

Replies: 0

When I try to send a test email using sendinblue, I get the following error log:

Versions:
WordPress: 5.7.2
WordPress MS: No
PHP: 7.4.9
WP Mail SMTP: 2.8.0

Params:
Mailer: sendinblue
Constants: No
API Key: Yes

Debug:
Mailer: Sendinblue
[0] cURL error 60: SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

I’m using WordPress on a localhost through WAMPServer, could this have anything to do with it?
