I am using server.pro for hosting a Spigot 1.8.8 Towny-based server with ~50 plugins (will provide plugin list).
Background info: Yesterday (12/26/2016) my server had a crash at 9:15 PM PST. I eventually fixed it by deleting the usercache.json (it was causing an error) by 10:20 PM PST. I made a backup of the server at 10:20 PM PST since it was a functioning version. A player kept joining the server and kept crashing the server as soon as he logged in. I tried to fix this by restarting and deleting the world he was in and reuploading it, but the server then totally crashed. I tried to back up to the 10:20 PM PST backup, but the problem where console shows nothing persists.
What is happening: I click the start button in the control panel. Server says "starting", then it says "running" for about 5 seconds before saying Stopped. No logs are made, and nothing is in console. server.properties is getting changed as well -- For example, the "server-ip = " keeps getting deleted.
Also, I have no backup that I can go back to since automatic backup erased and created a backup of the broken version and manual backup is the one from 10:20 PM PST.
Is this a hosting problem? Is this a problem I can fix? ANY advice would be appreciated.
Crash reports and logs are blank. No new logs or crash reports are being made. I only have ones from previous errors. Server doesn't show any signs of starting, for it to even make a log or crash report.
