The same error on CPT’s on different websites with different set ups.

Hello,

We tried to replicate the issue on our test environment with the PHP version set to 8.0 and 8.1.

We created a Custom Post Type and then created entries under it. We turned debug mode to true and opened the CPT pages on the frontend and backend, and we did not get any errors even with the meta information being blank or set to the default value.

For us to know more about your setup, please head over to your WP Dashboard > Rank Math > Status & Tools > System Status and click the “Copy System Info to Clipboard” button, and paste it here so we can further analyze the issue.

@dxvwebmaster, if possible, 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):

We really look forward to helping you.

Hello,

It seems that the error is rendered when your WPbakery is enabled. Allow us to check this further with our developers.

We should get back to you shortly with a solution.

Looking forward to helping you.

Hello,

Your site was showing 4 PHP Deprecated warnings. Of these, 3 were being triggered by the Rank Math Link Attribute code, which adds “nofollow” and “target” attributes to external links. To fix this, I added the following condition on line 114 in the includes/frontend/class-link-attributes.php file:

if (empty($content)) {
    return $content;
}

I have also logged this issue and we will include a fix in the upcoming update.

Now, your site is showing only 1 warning, which seems to be triggered by the WP Bakery plugin when the get_the_excerpt() function is used in the wp_head hook. We use this function to add the excerpt content to the Opengraph description. This issue is not specific to the Rank Math plugin; you’ll see this issue with other plugins as well that use this function in the head hook. Please forward this to the WPBakery team so they can take a look at it.

Hope that helps.
