Just to give a background and information before I give the full problem.

 

I rent from NFOservers. We've been wanting to add mods to our server for a while, but most of them require Minecraft Forge. So, I tried installing it a few days ago. I have followed the directions: Downloading it, changing the extension from .zip to .jar, and putting it into the server for selection. Now, here's the problem. Whenever I select it, the server goes offline. Despite constantly selecting the "Start the server" option, the server will not go online. What's going on?

Logs

The logs said nothing about it when I checked. I looked at the command console and as it was trying to run, it would say "invalid or corrupt file" followed by Minecraft Forge. I tried redownloading it and reinstalling it into the server, but each time, it's the same thing. I've even tried removing all of the mods in there and tried putting it in there. It still did not work.

Whatever tool you used to combine the jars corrupted them. Redownload forge and try again.

I'm a bit confused. It said just to change the file extension of the .zip into a .jar, so that's what I did.

Well, your host is being stupid, so try using good ol' 7zip to merge the forge files into your server jar.

The only download I need is the Universal Forge File, correct?

No take forge universal open it in 7zip of winrar and open the minecraft server jar I the same program and drag and drop all the forge files in to the server files then there's you forge server.

I did as you said and it still did not work. The server still won't start up when I have MF selected.

Logs

I checked the logs again and they said nothing about it. I checked the FTP and it just says that the connection was closed by the server. The console says it's invalid, and the logs just talk about random saves that automatically go on throughout the day.

Thread closed for being to fucking stupid to post your god damn logs.

THERE IS TEXT ON THE SCREEN post it.
