(Solved) NLBWMON missing after upgrade

I upgraded to Reboot 17.01.4 and now NLBWMON is missing from LuCI. I removed it and re-installed it but it doesn't help. Am I missing something or will it need to be updated also to be compatible with 17.01.4?

Did you install luci-app-nlbwmon?

All add-on packages need to be installed after a firmware upgrade unless you have included the packages in the firmware itself.

I just installed nlbwmon. Thanks, I found luci-app-nlbwmon and installed that. Now I have it in LuCI.

What do you mean by "downward" upgrade?

Should have been firmware
