My server wont start

[eniaolivia]

Recently my server didnt start and when i finally got it to start it had deleted everything and now i had to start a new one. Now when i manually try to start it in minehut.com , it says error and wont start. When i try to start it in lobby it says "sending you to_" and then send me back to lobby. What can i do? Last time i played on the server was yesterday and then everything was fine, but now it wont start.

To find out why it's not starting, the logs are very useful

Start your server, and when it's marked as offline again, go to your file manager -> logs and copy the full latest.log to https://pastebin.com/ , hit Create Paste and share the link here
