 * Hello [@salihkulangara](https://wordpress.org/support/users/salihkulangara/),
 * I’m sorry about the errors. Please try the following:
    1. Install & activate the [Yoast Test Helper plugin](https://wordpress.org/plugins/yoast-test-helper/)
    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.
