@soeblangdi Hi there. Thanks for your topic. This message displays in the editor when Web Stories cannot load images and videos in your Media Library. The most common cause for this issue is using a Content Delivery Network (CDN) or other service to host your site’s assets. Without the correct HTTP headers set, the connection to CDN-hosted assets will be blocked due to Cross-Origin Resource Sharing (CORS). For your reference, we also walk through the troubleshooting steps for this type of issue here: https://wp.stories.google/docs/troubleshooting/common-issues/
To confirm this is your case, can you please open your browser developer tools to check for any browser console errors? You can copy/paste the messages here or share a screenshot using services like JumpShare or Imgur.
@soeblangdi Your topic will be marked as resolved since we haven’t received any further response. Should you continue to experience this issue you are welcome to reopen this topic, otherwise please create a new topic for any other support with the plugin. Thanks!
