Registration Button not Showing in Frontend

I have a training class scheduled through my website, and people have been registering without issue. Now, for some reason, one of the classes only shows a detail button, but the Registration button is gone. Nothing has changed with the event, I even double checked to make sure registration was enabled and it is.

It's only happening with one of the four events I have and I can't figure out why.

Help please!

Hi

Below is my response in the support ticket. Please look at it and get back to me :

There are several reasons causing this issue :

1. The event date is passed. That mean today date is "greater" than event start date .

2. The cut off date for event is passed .

Could you please check and get back to me? If you still could not find the reason, please send me administrator account of your site so that I can check the setting for you.

Regards,

Tuan
