Details of the issue:

I'm trying to start a ftb server from a backup of a old ftb server I used to use on YAMS. A different minecraft server manager. It doesn't work and displays this error message and repeats it.

ERROR Unable to invoke method createAppender in class org.apache.logging.log4j.core.appender.RollingRandomAccessFileAppender for element RollingRandomAccessFile java.lang.reflect.InvocationTargetException
2:21:34 PM CONSOLE: java.lang.IllegalStateException: Unable to create a manager

I am using the latest McMyManager. And I have 16 gigs of ram. Also, this alls tarted after I went into the config for mcmymanager and increased the ram to 2.5 gigs​

Is the old backup the same mod pack?

If yes, then try to start the backup with the scripts available with the server download and when you see that it's working, then try the manager out. (i'm guessing it's at the manager it goes wrong)

And always post full logs using a paste service, easier to help with all information about your setup.

It was unable to create a log btw.
It isnt the manager because I posted it on their forum and they directed me here. Also I tested it on the Ftbstart.bat file and it came with the same error.

What about that?
