New project not loading

Hi,
I have created Kobotoolbox on my own server using Ubuntu Server 18.04. The process finished successfully. However, when i click on the button New to create a new Project, the dialog box keep loading but does not display the options of Building from Scratch or uploading an XLSForm. Also, when I drag and drop an XLSForm, I cannot see the deploy button.
Can anyone please help me?
Sam.

Welcome to the community, @samwahito! It could be your installation issue. Try validating your xlsform with this online validator to see if it shows any syntax issues.
