I confirm that MoonBTC/LTC/DOGE are not loading "Time since your last claim" and "Current claim amount" and the Login button doesn't work, but if you hit enter (no javascript involved), the login works.
This happens on either Firefox or Chrome on Windows. It looks like some jQuery failing to load related issue.
I logged back using enter as you said, still loading time.. and incorrect captcha entered message appeared.
Click resulted in pop up, then page loaded again...Time since your last claim....... nothing nor captcha.
