    Same here. I’ve also tried to install the Yoast Test help as suggested in another post and cleared some indexed, but still doesn’t work.

    Hello @sudiptomahmud

    We understand that the SEO data optimization process is failing to complete.

    Can you please try resetting our indexables in the database tables by following the steps below?
    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 each reset was successful. Note: Resetting the optimization doesn’t undo any of the hard work you’ve put into the plugin as the SEO data is also stored in WordPress’ default tables. It’ll just reset the custom Yoast tables that contain the combined data pulled from those default tables.
    4. Go to SEO > Tools, and under SEO data, click the “Start SEO data optimization” button to allow Yoast to rescan your content.

    Otherwise, if the error still occurs, you can refer to this article for more information –

    Hi @sudiptomahmud

    After resetting the indexables and rerunning the SEO data optimization process, are you still getting the similar error message and response code from the drop-down arrows?

    You might want to try resetting the indexables using the Yoast Test Helper plugin, enabling troubleshooting mode in the Health Check plugin, and use a default WP theme and only the Yoast SEO plugin enabled, and try and run the SEO data optimization process and see if you are able to complete the process. It might be a theme or plugin conflict that is preventing the process from completing.

    no it doesn’t work. i will change plugin. I saw a lot of people with the same error

    Plugin Support Michael Tina



    When the SEO data optimization process fails, the error details in the drop-down arrows would provide more information about why it failed. There are lots of potential reasons (plugin or theme conflicts, REST API is being blocked, incorrect permissions) which might be unique for each user and website setup. In certain cases, it also just needs a reset (using the Yoast Test Helper plugin) and to redo the process.

    There’s no one solution fits all method here. We recommend that you open a new forum thread for your scenario and provide all of the details so we can try and help you out. It’s discussed further in this article. Thanks for your understanding.

    I finally found the cause of the problem.
    The problem is “Tickera – WordPress Event Ticketing”
    Yoast SEO conflict with “Tickera – WordPress Event Ticketing”
