Error in a few monitors

Hi!

Do you mean the area to the right of the header logo? Try adding this additional css to make it span all the way to the right:

#header-inner-inner-inner { background: red; }

No changes, just a red bar in top and the rest still the same thing, with that space empty in right.

Look in my monitor is all right:

But when is a wider monitor theres that error in right side. ??

Try Customize > Theme Options > Styling > Website Max-width > Set to any you want.

Thx man!!! I changed to Boxed mode there! It works fine!
