Email not working

i have problem with contact form. When i want send it i get this error : E_WARNING - escapeshellarg() has been disabled for security reasons. can you help me somebody? I think this is something with PHP settings. PHP version on my hosting is 5.6.24. Thanks.

That PHP function is called by the library the Email plugin uses, so it must be enabled in order to work.

You should get in touch with your hosting provider about that.
