Date cant be save after White Labeled

Hi,
I just realized, after I White Labeled my self hosting Invoice Ninja, now when I created new invoice, the date cant be add and will be blank after I click SAVE, may I know why? And how can I solve it? Now the new invoice will without the date.

Hopefully can get your assist on this issue. Thank you very much.

I’d be surprised if it’s related to the license.

Which format are you using, there is a problem in our latest release with the second option.

It will be fixed in our next patch release.

It is really because of the Date Format, I think is because after I update the version. Very sorry about my misunderstanding, I will change to other date format. ^^

Thank you for your instruction.
