I just tried it on a WordPress installation with a default theme and no plugins running. The .docx file that I was using initially was saved from a Google Document, and that gives me the error. But when I tried it from a Word document downloaded from Microsoft it works fine.

Thank you.

The Getwid people got back to me saying they are aware of the conflict but haven’t had a chance to resolve it.

The second constant you posted is identical to the first one.

It seems to only be happening when using their Custom Post Type block.

So to replicate the issue:

• Install Getwid plugin https://wordpress.org/plugins/getwid/ and Nextgen.
• Insert one of their Custom Post Type blocks.
• Try to update the page.

Thanks for your assistance. I’ve heard nothing from Getwid so far.

OK thanks for your help on this.

To be clear, sometimes the error says “Updating failed. Unexpected token ‘<‘, ” <div class”… is not valid JSON” and sometimes it says “Updating failed. The response is not a valid JSON response.”

Great, thanks for looking into this.
