Subject: [PATCH] Warning messages fix: Warning: array_keys() expects parameter
 1 to be array, null given in ...\Ftp.php on line 44 Warning: Invalid argument
 supplied for foreach() in ...\Ftp.php on line 45 Now the last and only form
 of ftp-connection forms can't delete any more. This will solve this problem.
