server won't start, no repair files button

[redjenny]

Title kind of says it all. The free server I started for my friends and I just won't start, it says starting and then just immediately goes back offline. Every thread I've seen about it suggests using the repair files option, but there isn't one. The only options in danger zone are hibernate and reset.

It looks like there has been some chunk corruption. Also the repair files button didn't really do anything useful so they removed it. All it did was redownload the eula and spigot.yml
