Not sure if this will help, but I had a similar issue where all my blocks disappeared. I checked the console and there where a ton of errors around the location of things in the wp-json folder. After some forum hunting, I regenerated the permalinks (set them to something different and then set them back). All my blocks appeared again.

Hope this helps.

Also seeing this after an upgrade from 4.7 to 4.8 today. Submitting the post shows up in the console as going to:

/wp-json/contact-form-7/v1/contact-forms/1153/feedback

which returns a 404 error. I have rebuilt the permalinks and made sure WP_DEBUG is off. Still no luck.

Just in case anyone else ever runs into this, I have discovered that Elementor does not always play nicely with Browser Sync. Since both are attempting to re-write parts of the DOM on the fly, they cause the odd behavior I described above. I disabled Browser Sync and everything works as expected.

I am still trying to track this one down. It occurs cross browser, so it has to be some kind of issue with the theme. I would love to get some input on this if anyone has an idea.
