Can't tell you anything without an actual error message.
The latest release of Warehousing (0.1.2) requires Factorio 0.16. If you still play on 0.15, the last version you can use is 0.0.13.
If this does not help, please bring your issue to the forum thread, as the mod portal does not support discussion notifications of any kind. https://forums.factorio.com/17295
