There are two reasons that some of the blocks you've added to your site in our design platform may not have been published to the live version of your site.
The missing block contains only demo data.
Blocks that contain the Impress.ly demo data and nothing more are not published to the site as they do not contain original content. Please be sure to delete and/or replace demo data in order to be able to publish this block.
You've chosen a plan that does not include the blocks you've added.
If you've published the site under the Starter plan, you don't haven access to blocks that require a Business plan until you've upgraded to the appropriate plan.
