When I disable -Show messages for the gaming area it still show me a Warning masssage for area where I have no BigWigs or LittleWigs
Tested it on BigWigs v294 Rissian WOW client.

I have no idea what you are asking.
Please attach screenshots showing the problem.

And sometimes when I press OK, this window close and block screen, I cant click throught this spot (need relog)

framestack

The feature you have disabled is only for when addons are missing/not installed. In your case the "Aberrus" addon isn't missing, you have it installed, but disabled in the addons menu.

This is working correctly and will not be changed.

this window close and block screen, I cant click throught this spot

This is not working right. Please type /fstack in-game, it will make your screen change color and show all the invisible frames. Move your mouse over the spot you can't click and take a screenshot.

Your screenshot doesn't seem to show you mousing over anything.
When you mouse over something, an arrow appears in the tooltip to tell you what you are mousing over:

You will need to mouse over the area that is blocking your mouse clicks.
Also, please stop using random websites and just attach screenshots directly to this ticket.

Any update?
