Commented Issue: 2.0.1 does not work with DNN6.2.5 [7264]

I've installed 2.0.1 over 1.4.8 in DNN 6.2.5 and the editor didn't show up. I've removed module and installed it clean, and it still doesn't show up.

I had to remove all exisiting config files after completely removing 1.4.8, and after clearing cache in the browser it worked fine.
