I've trouble to upload a new plugin, I've tried to upload the drag and drop component (the version made for the authoring tool) but it always failed.
However, the drag and drop component appears into the component list and i can create and configurate the component, but when i ride the preview, there is nothing ("loading" all the time). When i check the problem on the browser console, an error message said that the drag and drop component doesn't exist...
So the upload fails, but the component appears but it does'nt work... I feel stupid...
What do I wrong? Can you help me?
