 * Hi there,
 * After the latest plugin update, we were asked to optimize the database. As we
   have seen a huge drop in our rankings since then (must not be related), I wanted
   to start the optimization anew.
 * For this: I installed the helper plugin, reset the tables and started the optimization.
 * Unfortunately it fails after some minutes of running (indexation-1680.js:1 POST/
   wp-json/yoast/v1/link-indexing/posts 500)
 * If it already ran for so long, is most of the optimization work already done 
   then and only some minor thing missing or is this a major issue?
 * Thank you in advance.
 * Best regards,
    Christopher
 * PS: Just checked the access log of the server and there are multiple 200 calls
   for the same URL. So at least something should be running through.

 * Hi [@ceem123](https://wordpress.org/support/users/ceem123/)
 * We understand that the SEO data optimization is failing, and you’ve reset the
   indexables data using the Yoast Test Helper plugin, but that it still eventually
   fails to complete, with the JS error of (indexation-1680.js:1 POST /wp-json/yoast/
   v1/link-indexing/posts 500) appearing.
 * Often, we see problems occur in combination with another plugin or theme. The
   fastest way to rule out any conflict, is to **deactivate all non-Yoast plugins
   and switch to a standard theme** like [Twenty Twenty](https://wordpress.org/themes/twentytwenty/).
 * Please test this on your development or staging site, if you have one. If not,
   we recommend using the [Health Check & Troubleshooting](https://wordpress.org/plugins/health-check/)
   plugin. This plugin has a troubleshooting mode, which **does not affect normal
   visitors to your site**.
 * If you’re unfamiliar with checking for conflicts, we’d like to point you to a
   step-by-step guide that will walk you through the process: [How to check for plugin conflicts](https://yoast.com/help/how-to-check-for-plugin-conflicts/)
 * Would it be possible for you to reset the data using the Yoast Test Helper plugin,
   enable troubleshooting mode in the Health Check plugin, start with a default 
   WP theme, and enable only Yoast SEO for WordPress, and see if you are able to
   complete the SEO data optimization process under SEO > Tools?

 * Hi [@mikes41720](https://wordpress.org/support/users/mikes41720/),
 * Thank you very much for the quick reply and assistance.
 * Found the issue: I hooked into woocommerce_product_add_to_cart_text via add_filter
   and apparently this broke the optimization on some pages.
 * Best regards,
    Christopher
