In the carpet? You are putting the .jar files for the plugins in the plugins folder, correct?

 

startup log please.

 

Yes, the plugins are in the plugins' folder.

But the problem is an other think. I've got 57 plugins enableds but I install new plugins and this plugins are not installed

I don't know what's the problem, but I think that, the problem affect to the server and the mobs can't drop anything.

I don't know. Now, I go to see.

I'm going to give you the log of the server in one moment are in dropbox. I'm spanish, no English

 

paste your log on pastebin.com and send the link.

 

am using Google Translate.
Already I know about the problem but I don't know how happened. It is as if the server would create a sub folder off the server that is reset as before. When I put the bukkit plugins or update the bukkit was the same, the plugins were the same too, when I using or creating something, then he was not saved. I don't know will be happened.
Google Translate it's an unprofitable page ¬¬.

 

Yh, goodluck with this is you can't paste your log we can't help you.

Por favor, borrar su server.log, a continuación, iniciar y apagar el servidor. Después de que vaya a pastebin.com y pegue el contenido del archivo de registro del servidor. Nos proporcione un enlace. (From Google Translate)

Please delete your server.log, then start and shutdown your server. After that go to pastebin.com and paste the contents of the server.log file. Provide us with a link.
