@CyanPrime not sure how that's fixed it as your route inside theme.less doesn't actually point to the vanilla template. For that file to point at vanilla, you'd be looking at ../../../nodebb-theme-vanilla, but if it works then, so be it. 😆
The one thing I like about iTunes and iDevices is that it allows you to make a complete backup of the thing.
Now, this is mitigated somewhat on Android by having your phone rooted so you can take a Nandroid backup, but it's not exactly user friendly, at least not compared to the one-click solution Apple offers.
