Hello! Excuse me for my bad English, I hope, my text will be quite clear for you.
On June 4 on the page of the server invalid information was shown, the server wasn't launched and sometimes the map didn't remain, (I built a huge structure 2 days, and it disappeared so as if there were no these two days as if someone made server rollback, but I precisely didn't do it)
On June 6 the server wasn't launched, plugins from time to time disappeared, settings disappeared.
I decided that this problem can be solved having reinstalled the server. I reinstalled, generated a new map, reconciled to that it is necessary to put all over again, the whole hour suffered with plugins, returned them in that status in what they were before server reinstallation.
I delivered a map, settings, plugins, all as it is necessary for me. I launched the server, apparently, it worked normally, played half an hour. I switched off. I included again after a while, but the map didn't remain and disappeared, plugins all disappeared. I spent for it one more hour and delivered plugins, and till today everything is normal except for two things:
1. The map not always remains even if to consoles it is written that the map remained. Yes, I entered /save-on and even /save-all before quitting from the server.
2. Not all plug-ins work.
3. The server isn't always launched
4. Settings disappear and are put on the standard
On the server there are plugins:
AdminFun, AuthMe, AutoMessage, CoreProtect, CraftBook, FakeTalk, PermissionsEx, WorldEdit, WorldGuard
When I launch the server, 3 of 9 work only:
AuthMe, FakeTalk, PermissionsEx
Files and settings of plugins don't disappear anywhere meanwhile, all files remain, but remaining 6 plugins are simply ignored, I should delete *.jar-files of plugins and to put them again, to write /reload and so each time when I launch the server.
At present I can't launch the server at all, and I suspect that my map was again lost, the server writes: Our fileserver is currently unavailable. You cannot start your server now. Please try again later.
Also when I open any page of a site Aternos - the site doesn't open and I see errors 502, 523, 524.
While I wrote this topic at a forum - my map again disappeared for the unclear reason...
What to do to me with all this? 
I very much hope for your help...
