One of my apps has got the blocks section almost blank

I have lost everything... How can I do?

Hello Tecnologia,

Is there an error that says "The blocks area did not load properly. Changes for 123456789 will not be saved"? If so, your project is corrupted. Please upload the AIA file of your project, and Power Users will take a look.

Export your .aia file and upload it here.

If not, did you delete the blocks on accident? Are you sure you opened the correct project?

Hello Tecnologia

To be sure that the Project simply failed to load fully:

  1. Use Firefox or Chrome
  2. Only have App Inventor in the Browser
  3. Ensure nobody else is using-up the broadband

You have not kept a backup of your Project file on your PC?

Did you do a tutorial that restricted your blocks pallete?

Try a right click cleanup blocks.
