    Hi,
    I just installed MB Blocks using MetaBox AIO, created a new block with a single text field using the Builder, then tried to use the block. I can add the block fine, but whenever the block switches to edit mode, this error appears in the console:

    Warning: Invalid DOM propertyclass. Did you meanclassName?

    Doesn’t matter if the edit area is within the content or the side bar.
    I didn’t add a custom class name to the block.
    The same error appears if I create a block using using PHP.

    Using Firefox 75, WP 5.4, MetaBox 5.2.8, MetaBox AIO 1.11.2.
    There are no other extensions enabled that touch Gutenberg.

    Hi Drake,

    I’ve just tested again with the latest version of Meta Box AIO and don’t see any errors in the console. Please see my video:

    I remember I fixed this bug in the latest version of MB Views.

    Thanks for the video.

    I setup another WP site, completely stock, and I didn’t get any errors on that one. As a test, I went back to my original site and deleted all the plugins and themes (except MB and MB AIO) and installed the stock twentytwenty theme, but I still got that react error. I tried completely clearing my local storage, session storage and cookies for that site and trying again, but it didn’t help.

    Not sure if it’ll help, but here’s the full stack trace from the error. I also tried using Chrome and got the exact same error.

    I’ve found the reason one site has the error and one doesn’t. My original site has define( 'SCRIPT_DEBUG', true ); set, my new test site didn’t. That might be why you weren’t seeing the error too.

    In addition to the first error, if I kept editing blocks after the first error was triggered, it would later trigger this error Warning: Can't perform a React state update on an unmounted component.

    Full trace: https://pastebin.com/8hHYdSUh
