empty lines result in false htaccess

[vermasslt@…]

When someone enters an empty line in the IP-Banlist in ACP the Listener creates an "deny from" line without any parameter in the htaccess. This leads to a http 500 error.

The best way would be to check the $line for a valid IP. The quick and dirty solution would be something like this:

foreach(explode("\n", StringUtil::unifyNewlines($optionsUSER_IPBAN_CONTENT?)) as $line) {

if ( strlen($line) > 4 ) {

$content .= "deny from $line\n";

}

}
