Project not Loading Help

First, what kind of error are you seeing...

• A Green error screen with a Try Again button
  • Go here
• A Black error screen with a Reload Now button
  • Go here

Green Loading Screen

Are you stuck on the green loading screen? Here are a few things you can try...

• First, click the Try Again button a few times and see if that helps.
• Give Thimble a little more time than usual to load, sometimes with a slow network and larger files, it might take longer to download everything. If that doesn't work...
• Clear your browser's cache
• Reset your browser's IndexedDB

If that doesn't work, please contact us.

Black Loading Screen

This error means that the editor was unable to load.

• First, are you using Private Browsing when using Thimble?
  • Turn it off and reload the page, Thimble needs to store some of your files in the browser storage, which is disabled when you're using Private Browsing.
• Click the Reload Now button a few times and see if that helps.

If that doesn't work, please contact us.
