Seemed perfect but…

What is the problem you’re experiencing? I’m using it with WordPress 6.0 without any issue.

I’d like to see what’s wrong and try to fix it.

^if Gutenberg is deactive.

I cannot reproduce the error on my local site. When does this error happen exactly? Are you trying to add a widget? or are you trying to update it?

This occurs whenever I add the widget to any “bar”, sidebar, footer, block etc.
