Same issue and the installation is in Chinese, I have tried google translate but to no avail as the steps don’t make sense.
There are too many guesses to make. Although the plugin is exactly what I am looking for, this plug in should be removed from the website it is rubbish if a plugin here is posted with an understandable installation procedure.
Since the code is submitted ‘as is’ this question has been asked on the developers website and the questioner has been send to the Chinese manual.
