    Hi, I got this error: 

    EMAIL DELIVERY ERROR: the plugin WP Mail SMTP v2.9.0 logged this error during the last time it tried to send an email:

Mailer: Gmail
cURL error 77: error setting certificate verify locations:
CAfile: /etc/pki/tls/certs/ca-bundle.crt
CApath: /etc/ssl/certs (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)
Consider running an email test after fixing it.

    The mailer is working fine before. Please help. Thanks.

  • Hi @evanyzd,

    Thanks for reaching out, and I’m sorry to hear about this cURL issue.

    The cURL error 77 indicates the issue with the certificate your server is presenting. Please contact your web host provider to fix the certificate for you. You can provide the details of that error log to your web host support.

    I hope this helps!

    Thanks ??

    Pls help

    Hi @evanyzd,

    Thanks for the details!

    We usually see this type of error in cases where there is a plugin conflict. If you are using another mailer or SMTP plugin, you will likely have to remove it. If it is a must-use plugin, you can remove it by contacting your web host or via FTP from wp-content/mu-plugins.

    This should fix the issue.

    Thank you!
