For some reason I am not able to load previews anymore. I'm using Chrome and developing the course in Adapt authoring tool. I get the error message "oops, something went wrong"
Any suggestions on what caused this and how to fix?
It could be lots of things. Have you checked the logs in Chrome's developer tools? (Chrome>More tools>Developer Tools or Opt+Cmd+I). Check here to see if there are any errors.
Do you have access to the server logs? This would probably give you more information.
