    After upgrading to 5.8, when I try to modify my widgets, I encounter errors on the Appearance > Widgets page concerning my custom html block. This occurs when I disable all of my plugins as well.

    The "custom_html" block was affected by errors and may not function properly. Check the developer tools for more details.

    Appears three times on the UI. These errors show up three times in the developer console.

    Hi, @dlin04!

    I just tested this out on a fresh install of WordPress 5.8. I was able to set up a new Custom HTML block as a widget without encountering this error.

    I saw that you disabled all plugins, which is a great start toward debugging. Try setting your site to one of the default (Twenty*) themes and give it another try — it may be a conflict with your specific theme.

    Hello. I had previously managed to use the theme customizer to remove the legacy Custom HTML widget and replace it with the Custom HTML block widget.

    However, after disabling all plugins again and activating the Twenty Twenty theme, when I attempt to edit my widgets (Appearance > Widgets) I am unable to Update (save) my edits.

    The message: “There was an error. The response is not a valid JSON response.” appears in the lower left.

    Please note that if I remove the Custom HTML block, the widgets Updates (saves) normally.

    After some troubleshooting, I’ve narrowed down the issue.

    I can save my widgets when I have a custom HTML block, but not if I include the following code in the custom html block:

    <script type="text/javascript">(function(d){var f = d.getElementsByTagName('SCRIPT')[0], p = d.createElement('SCRIPT');p.type = 'text/javascript';p.async = true;p.src = '//widgets.wp.com/platform.js';f.parentNode.insertBefore(p,f);}(document));</script>

    When trying to ‘Update’ widgets:
    There was an error. The response is not a valid JSON response.
