Backups fail if shell command not executable

[pdewouters]

WordPress 4.2 - backupwordpress Versión 3.2.4. Error: {"php":{"d48b02d27a9fb68b7aa4cd1f88ec329a":"shell_exec(): Unable to execute 'whoami', \/hsphere\/local\/home2\/aarte103\/elsolnews.com\/wp-content\/plugins\/backupwordpress\/functions\/interface.php, 114"}}

See http://stackoverflow.com/questions/11471739/shell-exec-error-when-executing-php-script

That error has nothing to do with the php executable, the error is returned by shell_exec( 'whoami' );, nothing to do with PHP

[pdewouters]

Yeah I guess that would only apply if the command runs a php script. so probably the user can't run the whoami command?

[willmot]

yeah, I'm guessing it's that they don't have permission etc. Would go away with #55 anyway so not a huge issue. Although we could at least make sure we are catching the error and not showing the message that uses the output of whoami (which we may already be doing).

#833 would fix

Going to close as #833 is going in
