Update the plugin to 1.7.0.

The page will no longer be editable.

Note: That content will no paste properly into 1.7.0. You have to paste it into 1.6.2 and then upgrade.

This is now resolved for me, but there’s still a bug related to updating from an older version of this plugin which may impact long-time users the next time they try to edit a page with an old timeline on it.

I tried deactivating all the other plugins, and it didn’t help. I believe the problem is that an older version of the plugin created much more verbose markup which crashes the newer version.

My workaround was to downgrade the plugin (with the WP Rollback plugin), recreate the content (by copy/pasting the content from the old block to an identical new block) and then updating the plugin again.

Here’s an example of the older, more verbose markup:

Then you’re not looking very hard. For heaven’s sake, I even tried to prevent you from losing one of your users who was “very very sad” and I will defend plugins that were unfairly poorly reviewed.

But you’re right, I usually only write a review after it’s clear that the maintainer is ignoring any bug reports, patches, or any other ways I’m trying to contribute. Congrats, you made it into that very short list.

So you didn’t care to write a positive review to encourage the author and a free plugin. But posts a negative 1 star review when it broke.

This is the saddest part of the community. No one cares when a plugin works, and enjoy it for free. But have to leave a negative rating when things doesn’t work.

Anyways, It was an experimental project to try block editor for other use cases. I may try to fix it if I get time.

What do you mean no one cares? During the 3 months when it was working, you had 100 installs, and 6% of those installs gave you a perfect review. That’s very good for any community.

Then it was broken for 9 months, and of course you didn’t get more installs and more positive reviews when it was broken.

And I didn’t just jump to a negative review. I tried to help. When I discovered that I couldn’t edit any of my forms anymore, I spent a day testing different versions of CF7, CF7-blocks, and WordPress, and reported to your Github that the error is related to a pre-6.3.2 WordPress update, but that fell on deaf ears. I didn’t post a negative review until you ignored everybody for an additional 3 months.

I posted this negative review so other people know not to install the project until it’s fixed. I would have changed it to 5 stars if you had fixed it. But now I know that even if you fix it, I can’t rely on it working long term. Thank you, that’s useful to know.

Is this still being looked at? I’m also experiencing it at yukonstruct.com. Just open the site in Chrome and check the console for the error message.

If it helps, you can still include any field type by adding an HTML block and using the old-school CF7 tags.

Oh, my bad! I had an old version of MFB on my staging site.

I believe you’re mistaken.

I’m vetting this plugin for my own use, so I checked the code, and it looks like the CSS and JS has only ever been loaded on the ‘admin_enqueue_scripts’, so it should only get loaded on the backend.

I also checked the inspector on the frontend, and it confirms that nothing is being loaded on the frontend.

So far, seems to work fine for me.

Trying to use this in template parts; the icon is there, but when I click it, the block changes to an error that reads “This block has encountered an error and cannot be previewed.”

That’s the first thing I did. That’s why I started digging into the code to fix it myself.
