Hello, the hide hotkey is not working

I use the default UI and doesnt work since 5 days :/

Do you mean 'Hide keybind text' and 'Hide macro text'? Both work fine for me with the default UI action bars.

If you are using an addon to replace the action bars (such as Bartender), you need to check the settings of that addon to hide keybind and macro text.

I have the addon in french is maybe this the problem ?

i find is Bindpad the addon :(

BindPad has its own hotkey text setting. Open /bindpad and uncheck Show Hotkeys.
