I’m experiencing a strange behavior of a block in PluginDocumentSettingPanel. I’ve registered some colors in editor-color-palette. I want these to be selectable in the document setting panel. Here’s the code:

I encountered a problem related to Wordpress Gutenberg blocks.
Created custom Gutenberg blocks on a local server. Assembling webpack, that’s all. On the local server everything works and everything is visible, but when everything is uploaded to the server, the blocks stop working and give an error:
Uncaught TypeError: external_wp_blocks_namespaceObject is undefined

I’ve got a custom theme. Everything use to work perfectly fine (February of this year). Now I cannot search for new plugins within Wordpress. It just displays the spinning circle. When I activate a default wordpress theme, the plugin page works fine. Any ideas? Anything new that must be in themes over the past couple of months?

How do I speed up a WordPress website?
