Minecraft 1.7.10 EULA
As of Minecraft 1.7.10, Mojang now requires you to modify the eula.txt file to get your server to start up (effectively indicating that you accept their EULA). When you first start your server on that build, you will see the following messages in your console:
[Server] Server thread/INFO You need to agree to the EULA in order to run the server. Go to eula.txt for more info. [Server] Server thread/WARN Failed to load eula.txt
To get your server to start up, you can simply navigate to the Files > Config Files > eula.txt page in the Multicraft panel and change the eula=false to eula=true then save once completed and restart your server.
Alternatively, you can follow the steps below to do it via FTP:
1. Go to the FTP File Access page in your Multicraft panel and enter your password (it is the same as your control panel login password).
2. Once logged into the web FTP, click to edit the eula.txt file and look for the "eula=false" entry.
3. Change the false value to true, then save the file.
4. Start up your server again and it should start up fully.
