codeigniter 3.0.1 equiped with opencart filemanager

That's pretty cool.

However, you don't have any licensing information for your code and Opencart is GPL v3 which means you must release your code as GPL v3 as well.  Most developers won't use that these days since MIT is the new hot things out there for open source and GPL isn't compatible.

Is it opencart-like or are you actually using some of the code from opencart?

I'd love to use something like this for Open Blog, but wouldn't be able to as it's MIT Licensed.
