Hello,
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
Sorry for the issue you are facing.
Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.
To determine that, please follow this troubleshooting guide:

Please let us know if you find the culprit.
Only the site admin would know and your users won’t be affected by this troubleshooting.
Looking forward to helping you.
Hi Febby,
Thanks for the feedback, I managed to install the HealthCheck plugin and become myself familiar with the Debug mode so at least the error message wont appear to my visitors.
After checking a bit more on the source file ‘class-frontend.php’ it seems as the code which produces this error is the following:
return ‘FAQPage’ === $schema[‘@type’];
Any ideas on what might be wrong to this line of code so I can fix and upload?
Best Regards
Nikos
Hi there. I’m also seeing this notice on a clean WordPress instance with WooCommerce and a scratch built minimal theme.
It’s a simple undefined index notice which I’m sure the plugin developers will be able to sort out.
A quick solution is to change line 200 to:
if (isset($schema['@type'])) return 'FAQPage' === $schema['@type'];
Hello,
We are glad that you found the solution.

Hello,
All schema types have @type and it is a required property. Adding an isset condition in class-frontend.php will fix the error but in the Structured data testing tool, you will still get errors.
Have you added any custom schema in the post or anywhere on the site? Can you add your site’s admin access details in the Sensitive Data Section so we can take a look at the Settings on your site?
Looking forward to helping you.
Some further information in relation to this. I believe the following schema is being defined by WooCommerce:
Array
(
[@context] => https://schema.org/
[@graph] => Array
(
[0] => Array
(
[@type] => Product
[name] =>
[url] => [removed from example]
[@id] => [removed from example]
[description] =>
)
)
)
I don’t know enough about schema markup to say whether this valid or not, but it looks like WooCommerce is defining a schema differently to how you are expecting, with the @graph array containing potentially multiple schemas?
Hello,
We were able to reproduce the error and have logged it. Please allow us some time to test and release a fix. It should be added to the plugin in the upcoming update.
For now to fix this issue please add following filter code to your theme’s functions.php file:
add_filter( 'rank_math/json_ld', function( $data ) {
if ( isset( $data['ProductsPage'] ) ) {
$data['ProductsPage']['@type'] = '';
}
return $data;
}, 98 );
I hope that helps. If you need any other assistance, please feel free to let us know. We are here to help.
