A user reported an issue some days ago regarding a problem of the plugins and we realized that the real problem was that this plugin is using a deprecated version of our code. The plugin and the prelude were updated the 5th of November. Right now, our C2 plugin uses the 3.0.5 version of the JS plugins. This is the new documentation:
As you can see, the main change is that now CocoonJS is called just Cocoon and some methods now are shorter. In addition, there are new namespaces, so it can be that a method is now in another namespace more suitable to its function. This means this won't work unless all the files are edited to use the latest version of our code.
Here are the JS plugins files that you need to replace:
However, this code is already contained in the prelude, so maybe there is a way of using it instead of pasting these files again.
