In certain hardened environments the Revert changes feature could fail with a "General error" page showing:

Permissions - Unable to restore snapshot:
Permission problem: Path not writable /omd/sites/mysite
Permission problem: Path not writable /omd/sites/mysite//
Permission problem: Path not writable /omd/sites/mysite/.

This happened even though the site user had all the necessary permissions. This has been fixed.
