I was afraid of this answer.
To be honest the plugin is made for version 1.6, I tried to run it and fixed everything that checmk was reporting as an error, but we might have an incompatibility issue that is greater than I thought. Is there anyway we can convert from 1.6 to 2.0 without the developer? I tried to reach out ( and I’m not the only one) but without any success.
I think if we manage to fix this plugin it will help the community as MikroTik is a world renown manufacturer and highly used in networks around us.
