explosion in my friends minehut server

[LaneyThePooh]

Hi! So my sister and I created a server for all of our friends, but a couple of them thought it would be a good idea to place down like 5,000 TNT minecarts and explode them. Due to that, whenever one of us tries to log on the server, it crashes. How do I fix it? Or, is there someone that could fix it for me?

Please activate your server, go to 'Danger Zone' on your dashboard, then click on 'Reset Sever' and 'Yes' on the popup saying that it will reset your server. Then restart your server.

Note: This WILL completely reset your server and there is no bringing it back, unless you have a save.
