PHP Warnings from Yoast SEO Plugin

    Hi there,

    We noticed some warnings in our server logs. They seem to come from the Yoast SEO plugin.

    The logs show two warnings:

    1. PHP warns about an undefined key named “wpseo_premium” on line 578.
    2. PHP warns about a loop on line 582. The loop gets a null value instead of an array.

    Both warnings happen in this file: wp-content/plugins/wordpress-seo/inc/options/class-wpseo-options.php

    You can view our log screenshot here: https://maicoind.com/wp-content/uploads/2026/07/Error-Log.webp

    Here’s our environment, in case it helps:

    • WordPress version: 7.0.1
    • Theme: Astra 4.13.6
    • PHP version: 8.3.32
    • Database: MySQL 8.0.46-37
    • Yoast SEO: 28.0

    Will there be a fix for this? Thank you for your help.

    Thanks for sharing the site info. Nothing in the report immediately stands out as being incompatible with Yoast SEO 28.0. The warnings you’re seeing (Undefined array key "wpseo_premium" ) is not expected behaviour. A couple of questions:

    • Do these warnings occur consistently, or did they only appear once?
    • Was Yoast SEO Premium ever installed on this site, even if it has since been removed?

    To answer your questions:

    1. It wasn’t as consistent as on July 17th, but I am still receiving the same errors today.
    2. No, we’ve never had Yoast premium, which is why I am confused about the warning.
