Warning: escapeshellarg() has been disabled for security reasons
My ISP has disabled some php functions, a.o. passthru() and escapeshellarg(). This has to do with the risk of running these functions in combination with user-supplied arguments. So, in my case, this warning has nothing to do with the safe_mode setting in php.ini. My ISP claims that most security breaches could be traced back to the misuse of these functions. Security is, of course, also in our interest. I wonder how other ISP's can guarantee security, while leaving commands like passthru(), shell_exec(), and exec() open for user-supplied arguments.
