    Hi

    I recently migrated a client website from development to live (two different servers) using UpdraftPlus but are now getting this error on the website.

    Warning: array_key_exists() expects parameter 2 to be array, null given in?…/plugins/wordpress-seo/src/generators/schema/breadcrumb.php?on line?143

    I have deactivated all plugins, switched to the Twenty Twenty-One theme, and I am still getting the error.

    I have seen another post on this forum regarding this issue and it was reportedly fixed in version 15.9, which we are using but still getting this error.

    Any help would be most appreciated.

    Thank you.

    We expect a few more information about your setup. This might help us replicate the issue on our end:

    1. Can you confirm you are using the most recent Yoast SEO, v15.9? If you update, does the issue resolve? This guide explains more about how to update:?https://kb.yoast.com/kb/how-can-i-update-my-premium-plugin/.

    2. Are all your non-Yoast plugins and themes also updated?

    3. Can you confirm you are using WordPress 5.6.2?

    4. Does your setup meet plugin requirements?

    5. Clear all your caching from your theme, plugin, server, CDN like CloudFlare or browser.

    6. Reinstall the Yoast SEO plugin.

    We look forward to hearing from you.

    Hi

    I have fixed the issue. There was some erroneous code in the functions.php file which was causing the error after the migration.

    Thank you again for responding so quickly. Very much appreciated!
