Request For Testing

Hi Claudio, Could you please test this block?

1. Create a new page
2. Add a "Search" block

Expected:

• It matches the design
• The text here is editable:

Added a search block to post at http://dev-amp-start-travel.pantheonsite.io/wp-admin/post.php?post=202&action=edit. Published, but am not seeing it on Site

Hi @csossi, The block looks to appear on the front-end of that URL now, but one of the 'Search' blocks shows this error in the editor:

This block has encountered an error and cannot be previewed.

Does it also appear on the front-end for you?
