problem with minimap
 

I'm having an issue with the minimap when using Carbonite and TukUI

Minimap is round though all the settings from options are set for square minimap. Also when i uncheck the "Show standard Minimap nameplates" the minimap disappear. Same things happen also when using only Carbonite

Those options only pertain to the Blizzard Minimap when it is merged with Carbonites' map. If you want a square minimap, try something like Squeenix. Lightweight, and very simple.

then how to fix the problem with tukui?

I don't have a clue, unfortunately. You might want to visit the forums on the Tukui official website and see if you can find your answers there.

In my installation of Carbonite, if I check the option to "Show standard Minimap nameplate" all it does is make the clock show up on the Blizzard minimap inside the Carbonite minimized map (obviously, I merge the maps). However, I don't use the Carbonite Button Window for my minimap buttons, preferring instead to use MinimapButtonFrame which does not collect the clock as a button.
