Google search console sitemap date error

Hello Eric,

Thanks for reaching out regarding your sitemap.

An invalid date in the sitemap typically indicates a miscommunication between our plugin and the WordPress database. Can you please confirm that the time in your database matches the expected time on the URLs specified? You may need to speak with your web hosting provider. Then, you’ll need to update the pages or posts that show the invalid date; you won’t need to update all of your pages or posts.

Once the changes have been made, please clear the cache from caching plugins, the server, a CDN like Cloudflare, or the browser. If you are not sure how to clear cache from a plugin, please contact the plugin author. If you’d like to clear the cache from the server, please speak to your web hosting provider. To clear the cache from a browser, use this guide: How to clear my browser’s cache?

Once the cache is cleared, please follow the below steps:

1. Delete your sitemap in Google. Doing so will not hurt the SEO of the site. This guide explains more (scroll to the bottom): https://support.google.com/webmasters/answer/183669?hl=en.
2. Submit your sitemap again. Be sure to submit only sitemap_index.xml and nothing else. This guide explains more: https://yoast.com/help/submit-sitemap-search-engines/
3. Monitor the results to see if the issue is resolved. Please bear in mind that it can take some time before Google can report on the crawled URLs after you re-submit your sitemap because Google Search Console reports are not real-time.
