How a .htaccess trailing slash redirect rule caused WordPress Gutenberg saves to fail. The issue: 301 redirects on REST API endpoints dropped POST request payloads. Solution: exclude /wp-json/ and /wp-admin/ from .htaccess rewrite rules.

Have you ever encountered the frustrating error message, “Updating failed. Could not insert post into the database,” while trying to save a blog post in WordPress?

After several attempts and troubleshooting efforts, I discovered an unexpected culprit: Unicode characters, such as emojis or special symbols, were preventing my post from updating.
