Error loading block: Invalid parameter(s): attributes


I am getting the error “Error loading block: Invalid parameter(s): attributes” when i add blocks with php code inside of them. It seems to be only blocks with PHP inside of them. Other blocks work correctly.

I created a video to explain:

Hope you guys can help me out.


@Guido are you using Block Control plugin? It doesn’t work with dynamic blocks. Other plugins might have similar issues.

Hi @matjaz,

Yes it was a plugin that i have installed. Blocks CSS: CSS Editor for Gutenberg Blocks – WordPress plugin |

After disabling it all worked well again.
