 * Hello Manikandan2021
 * We are sorry about the database error. Can you please try resetting our indexables
   in the database tables by following the steps below?
 * 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 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.
 * For your site’s health and safety, we recommend creating regular backups of your
   site and database. This is especially important before making important changes
   on your website.

 * Hi [@manikandan2021](https://wordpress.org/support/users/manikandan2021/)
 * Depending on the size of your website, the SEO data optimization process will
   take a while to complete. If you check the progress bar underneath the SEO data
   optimization process, it should continue to show the progress over time.
 * If you open your browser’s console and check the network tab, you can check if
   it continues to process requests as well. Once the process has completed, could
   you check if the errors still appear?

 * [@manikandan2021](https://wordpress.org/support/users/manikandan2021/) Thanks
   for your reply and we’re sorry to hear about the continued difficulties.
 * Can you please let us know whether your site is particularly large?
 * For sites with more than 10,000 posts, we’d advise using the WP CLI command to
   do the indexation on the server. You can read more about this here: https://yoa.
   st/wp-cli-index
 * Can you please let us know if this resolves the problems?
