    Hello, I am getting this error below. I tried to google it but I don’t see much information. My website is created recently. So I got the WP 6.1 and Yoast 20.4. It is running on IIS 10 (Windows VM Azure ) and Php 7.4.

    Error Summary

    • PHP Fatal error: Uncaught Error: Class ‘Yoast_Notification’ not found
    • PHP Notice: Function is_embed was called incorrectly. Conditional query tags do not work before the query is run. Before then, they always return false.

    Hello @mchlsync

    Thanks for reaching out about that error. Please try the following:

    1. Install & activate the Yoast Test Helper plugin
    2. Go to Tools > Yoast Test
    3. Locate the Yoast SEO section and click on the ‘Reset indexables tables & migrations‘, ‘Reset Prominent words calculation‘, and ‘Reset Internal link counter‘ buttons. After each click, the page will reload to confirm that the specific reset was successful.
    4. Go to SEO > Tools, and under SEO data, click the “Start SEO data optimization” button to allow Yoast to rescan your content.

    Please let us know if the reported issue remains after resetting the optimized data.
