I just received this from Gethub:

“Please download and install AMP support/compatibility for WordPress PDF Embedder, you just need to activate it, no settings needed.

“You can check the demo of the same plugin [here] (https://plugins.dev6.rt.gw/2021/04/pdf-embedder-test/?amp )”

Thank you, Ben. The response this morning has been entirely different. Let me see what I need to do to remove this comment.

QUICK ANSWER FOR THOSE SEARCHING:

Based on my personal experience, in the “TinyMCE Advanced” to “Advanced Editor Tools” plugin under Advanced Options, uncheck “Add Classic Paragraph block” and the problem vanishes (after you replace all of your Classic Paragraph blocks WHICH MAKES USING “CONVERT TO BLOCKS” WITH THIS BOX CHECKED A ONE-WAY STREET YOU MAY NOT WANT TO GO DOWN.

Contrary to the following paragraph, I found I could configure the TinyMCE toolbar as before when I worked in the Classic Editor and do everything I was doing then in the new Classic block. I mean no disrespect for the developer is saying this.

“The Classic Paragraph block includes the familiar TinyMCE editor and is an extended and enhanced Classic block. You can add multiple paragraphs, tables, galleries, embed video, set fonts and colors, and generally use everything that is available in the Classic Editor. Also, like the Classic block, most existing TinyMCE plugins and add-ons will continue to work. This makes the Block Editor more familiar, easier to use, easier to get used to, and more compatible with your existing workflow.”

With that box unchecked, it is not only safe but highly desirous to check the following ” Make the Classic Paragraph or Classic block the default block (hybrid mode)” box. At that point, you have all of the advantages of the old paradigm, including first and foremost TinyMCE and the added bonus of spacer blocks, etc. in the block editor.

Andrew,

Thank you so much for responding. I have resolved this issue but want to respond for the sake of others. For this reason, I think this post needs to be somewhere. I rarely reach out for help like this, so would appreciate help moving it to another forum. It is not immediately obvious to me how to do this. People will be searching for “THIS BLOCK HAS ENCOUNTERED AN ERROR AND CANNOT BE PREVIEWED”.

This was particularly vexing for me because I was changing from a relatively unsophisticated WordPress theme to Astra and at the same time taking the much-dreaded step from the Classic Editor to the Block Editor.

Answers to your questions:

1. If it is a random error, are there any common factors that seem to trigger it?

None that I could identify, except that it did not take long for a Classic Paragraph to start to fail. The page would still generate properly, so I could just copy the text from the displayed page and create a new Classic Paragraph. But then after a few uses, it would fail again. The problem became a show-stopper when this happened to my entire sitemap. All the work in the sitemap is in the HTML and CANNOT be copied from the displayed page. This is what forced my hand.

2. Does it happen only with older posts or does it happen when you start a new post and then go back to editing it?

Semantics, but I only have pages and all of them are very old. However, the recreated Classic Paragraph blocks were of course new.

3. Could you copy the whole Classic Paragraph block’s HTML and paste it in a comment on the thread. The HTML can be accessed from the dotdotdot menu in the very top/right corner and selecting “Code editor”. Please copy everything between the block markers: <!– wp:tadv/classic-paragraph –> and <!– /wp:tadv/classic-paragraph –> including the markers.

Yes, I still have pages that were converted before I turned off the Classic Paragraph option.

Right now this displays in the editor with the message that “Your site doesn’t include support for the “tadv/classic-paragraph” block. Were I to turn on Classic Paragraphs, it most likely would show as “THIS BLOCK HAS ENCOUNTERED AN ERROR AND CANNOT BE PREVIEWED”. But I cannot be 100% sure of that without making the change. Respectfully, I lost a lot of sleep over this and have a stable system for the first time in weeks. I am not willing to turn Classic Paragraphs back on for that reason.

HERE I WANT TO STRESS THAT ONCE THIS HAPPENED, IT HAPPENER FOR *ALL* OF THE CLASSIC PARAGRAPH BLOCKS, NOT JUST SOME. This would suggest that the problem is not actually something the user is doing.

(Yes, I know there are grammatical errors in the following.)

<!– wp:tadv/classic-paragraph –>
<p class=”has-text-align-left”>The question you should be asking yourself right now is, <span style=”color: #ff0000;”>What is the Trump circus hiding?</span> Make sure you understand what I just asked. I did not ask what Trump is hiding. I don’t know who helped him get in office and I do not care. I am neither for nor against him. I have become apolitical ever since I started to see the bigger picture. What I just asked is why are people all over the world become embroiled in politics? It’s Trump in the United States, but it’s Muslims in Europe. Why are we being so distracted by politics that people who frankly didn’t really give a damn less than a decade ago are now rioting in the streets as has not been seen since the Vietnam War.</p>
