I have followed http://stackoverflow.com/questions/9942621/how-to-install-and-use-modules-in-silverstripe as guidance on how to install a module.
I have silverstripe 3.1.13 installed and have unzziped the SortableGridField module (Requirements: SilverStripe 3.0.x, 3.1.x, 3.2.x ) to the destination folder named SortableGridField in the directory containing assets,cmd,framework etc.
The problem I am having is that when doing the /dev/build?flush=all silverstripe will not pick up the module and it doesn't rebuild the database. Is there anything I need to have in mind that I am missing? Any help would be appreciated.
