Unable to start jail even after Hard Reboot

[WellisKelly]

All of a sudden I'm now getting this error when trying to start the jail running Plex. The jail is called "Plex" but it no longer will start

Error: [EFAULT] + Starting services FAILED ERROR: [b'jexec: execvp: /bin/sh: Permission denied\n', b''] Refusing to start Plex: exec_start failed

Any help would be greatly appreciated.

Thanks.
