How would I know what causes the error 500 while loading the app?

Alena, thank again. Is there an option to have automatic backups, say, 1 per hour? This would help a lot - i'd just restore from the previous point and that's all

[Alena Prykhodko]

This option is available http://docs.appery.io/tutorials/app-v...

Alena, yes, but you should do this manually, not automatically (as on google drive - it just saves and then you can simply restore)

[Alena Prykhodko]

Unfortunately, there is no such possibility for now.

Ilya, as you can open project, will be easier to recreate it manually to the step when app works. Project seems to be broken and requires time to find out the reason.

Hello! Could you try to check Public and save app, then uncheck it, save and try again? The same with Show in mobile frame checkbox. Please let us know result.

Maryna, thank you. I deleted the app and started from the scratch as Alena suggested.
