"Create an invoice" not working

[Aakriti]

Hi there,

I have to send an invoice before the end of the day and I've been trying to create for over 8 hours now.

The buttons are just not working. I thought it might be a technical issue and would resolve itself within a couple of hours at most. 

But now half the day has gone by and I am still unable to create an invoice. 

What should I do?

Any help would be greatly appreciated! 

Thank you,

Aakriti
