That’s interesting.And only a puzzle solver like me would write something like this. It actually sounds terrible.

Do you be any chance have the Classic Editor plugin installed? A recent update changed added another setting to it. You can double-check under Dashboard > Settings >Writing.

Do you have any other plugins installed that add Custom Blocks to your site? If might be caused by one of those, not intentionally, of course. If you briefly deactive a third party blocks plugin and see if it persists.

Of course, it could also be a result of a different plugin incompatibility. Hard to tell. There is the WordPress Health Check plugin, that allows you as an admin in troubleshooting mode to deactivite plugins and themes, without taking your site down for visitor. I have found it to be very very helpful when something ‘unexplainable’ happens on a WordPress site.

It would be really helpful for other forums visitors if you could report back with your steps to hunt this one down:-)

Hi there,
yes, the new editor needs a little getting used to, and has it’s own learning curve. Now might not the right time for you to spend time on it. If there is one specific feature that is totally mysterious to you, maybe we can point you in the right direction.
If you are able to install plugins, the WordPress Contributors provide the “Classic Editor” plugin directly from your “Add New Plugin” screen. That should get you back to the old editor.

Hi there. Seems you had an terrible start with Gutenberg. And the overlapping block toolbars can be quite irritating. Try this: go to the three-dot menu on the top right and select Top Toolbar. That anchors the block toolbars bar to the top of the screen and out of the way. See if that works better for you.

You can also use the ‘classic block’ for a more traditional experience.

You are welcome. I am glad to read that the Classic Editor works for you on your site.

Great, that you were able to narrow it down some more!

Are you using any 3rd party blocks on this particular page?
Or a blocks that uses outside services?

Are you using any other page builder plugins? Do you have other plugins which provide you with Custom Blocks installed?
There was a new Gutenberg version (4.5) released on Nov 20th. Do you still see the error message?
It might help if you provide a bit more information regarding your site.
Also, WordPress Contributors maintain a Health Check & Troubleshooting plugin that will allow you with tracking this down.
For instance, it will allow you as the administrator to switch off plugins one at a time, without affecting your live site. This way you can make sure there isn’t a conflict with another plugins causing this error message.

Let me know how this goes:-)

Oh, that’s terrible. I assume that you already installed the respective plugins to handle the short codes. Sorry, but I have a ton of questions for you.

What were the other blocks? Were they Gutenberg default blocks or custom blocks from a different plugin?
Is it possible that those blocks were created with a different version of Gutenberg than on the new site?
What happened when you clicked on Convert To HTML? Did some of the display alright after that?

Did you try to open the particular post via the Classic Editor plugin?

Interesting. You put all that in your Github issue, right?
