# ‘Start SEO data optimization’ not working

 * I can’t start the SEO data optimization because of a 404 error on this url ‘/
   wp-json/yoast/v1/indexing/prepare:1’.
 * I have tried using “Reset indexable tables & migrations” using the Yoast Test
   Helper plugin, but this does not fix my problem.
 * I also tried disabling and enabling different plugins, but this also does not
   fix my problem.
 * Can anybody help me out?

 * Hello,
 * We are sorry that you are unable to complete the SEO data optimization and thanks
   for sharing the JS error.
 * First, what version of WordPress and Yoast SEO plugin do you have on your site?
   Also, are all other plugins and current theme updated?

 * Can you please verify that your database has `ALTER, CREATE, DELETE, INDEX, INSERT,
   SELECT, UPDATE, DROP` permissions? These are required to create these tables 
   in your database: `wp_yoast_indexable, wp_yoast_indexable_hierarchy, wp_yoast_migrations,
   wp_yoast_primary_term`.
 * If you are not sure, your host provider can help.
