Uncaught TypeError: blockEditor is undefined

By any chance do you have the block editor disabled probably via the Classic Editor plugin?

Thanks for your quick reply! We don’t Classic Editor active any longer, but we used to use it on a previous iteration of the site.

I just checked my sites and I can replicate this. I think this is likely because I’m still using the older version of the Gutenberg blocks code rather than the newer one which was released in the last few versions of WP.

I’ve filed this into Github to be fixed in the next version.

Thank for the prompt attention and fix for this. You rock!

It won’t be for a while as I do this on the side but upgrading the blocks has been on my list given all the movements in Gutenberg.

I’ll mark this closed as I’ve filed it in GitHub. In case you’re looking for updates, it’s worthwhile following the thread there.
