Shiny server error: No UI defined

When I open my shiny application on shiny server, I got an error:

No UI defined

Shiny couldn't find any UI for this application. We looked in:

www/index.html
ui.R

I have checked:

  • The shiny server is running
  • I can run the default hello application.
  • I can run my local application without problem.
  • I have run the same application before on my shiny server and it worked. However it is not working with the same codes.
  • All file under my application have -rw-r–r– permission.

Can anybody help me with this? Why did it happened?

Thanks in advance!

I did get same kind of error but it was because I forgot to save the changes made in ui.R file. It runs last saved version of ui.R.
