Hello,
I have updated the sensitive data as requested. Can you please check further?

Hello,
Could you please make sure you follow this guideline: https://rankmath.com/kb/rich-snippets/#easy-digital-downloads-schema to configure schema for your EDDs?
If this still doesn’t help, please share your site WP and FTP access as requested in previous reply so we can check into this further
Looking forward to helping you. Thank you.
Hi, thanks for your help.
I have seen the guide that you have given me and I have everything well configured.
The problem appears when I activate the variable prices option in Easy Digital Download, since the structured data automatically gives an error. It seems that it is a bug in the code because the index of the php array (0, 1, 2, 3…) is inserted as structured data.
In the first message I put a link to an image so that you have an example. Also in the sensitive data area I put a link to my website so that you can test it in Google’s structured data tool.
Thank you.
Hello,
In that case, 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.

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:
https://wordpress.org/plugins/temporary-login-without-password/
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):
https://wordpress.org/plugins/wp-security-audit-log/
We really look forward to helping you.
