NinjaScanner v1.2 introduces a new and unique feature, the quarantine sandbox:
When moving a file to the quarantine folder, NinjaScanner can use a testing environment (a.k.a. sandbox) to make sure that this action does not crash your blog with a fatal error. If it does, it will warn you and will not quarantine the file:
The sandbox will be enabled by default, whether you update NinjaScanner from v1.1 to v1.2 or install it for the first time. Although not recommended, you can disable this option to bypass the testing environment and force the file to be moved to the quarantine folder.
