Error in block explorer. Again

Looks like your wp-json is 404ing

This means that your WP Rest API is not working properly.

Try entering https://[your-domain]/wp-json if you get a 404 then your WP Rest API is down.

Try to enable permalinks in Settings – Permalinks – Post name – save

Also, check your .htaccess configuration

If that doesn’t work check that you have mod_rewrite enabled.

Some additional help:
