 * Hi
 * I’ve found an issue using the json Guttenberg Block.
 * When added to a page it shows error “Error loading block: Invalid parameter(s):
   context”.
 * Browser console shows errors…
 * `GET https://domain.com/wp-json/wp/v2/block-renderer/jci/jcifree-block-script?
   context=edit&attributes%5BapiURL%5D=%2Fjson-content-importer%2Fjson%2Fgutenbergblockexample1.

 * Page seams to render ok when previewing.
 * Any suggestions?

 * Hi,
 * maybe a Security-Plugin like Wordfence is blocking the WP-Rest-API-Requests?
   
   Those are needed here. You might switch off all plugins except JCI and check 
   if the error is gone. Then switch on the other plugins.
