YOu need to open your publicvariable.log and find your user name and look for the reason it is kicking you. With all the different BE filters people use, simply asking what PublicVariable Value Restriction #17 is, is very, very vague.
I'd shut down the server, acces the BE filters via an FTP program, FileZilla, open the publicvariable.log and delete it's contents, then save the blank log file. Fire up your server, log in, and if you get kicked, re-launch your FTP program and again open your publicvariable.log to see why it's kicking you.
