I am getting error undefined while sending post for instant indexing

Hello,

Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.

The error message, “OpenSSL Unable to sign data” seems to suggest an issue with the SSL certificate, or some other server-side configuration issue with the OpenSSL module. Please get in touch with your hosting provider and see if they have a solution regarding this.

If everything is correct and the issue persists, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

Let us know how it goes. Looking forward to helping you.

Thank you.
