The plugin doesn't work with MK_Core by Aerosys...
Greetings.
This error is happening because both of our plugins are using the constant 'params'. You can edit both of our plugins to use var instead of const and it should stop that from happening. If you swap the order the plugins are loaded in, you'll find his plugin probably throws the same error too.
In my plugin this line is line 627, I'm not sure about his.
