1. 300×300
2.are you familiar with languange file .po and .mo, use them to translate all the english string.
3.you’re on rtl active site. its normal to be like that, why do you want to change it.

I do not know if you understood me correctly but, You can see a empty area on the right in the menu under the logo and also the menu above it. (I work on the logo)

What is the best way to edit po file?

Thanks

You can see a empty area on the right in the menu under the logo and also the menu above it. (I work on the logo)

try add this to theme option->custom css

#top-navigation .sf-menu li a,#main-navigation .sf-menu li a,#siteinfo { float:right !important; }

use poedit (download it free) to edit .po file.

I used the CSS you gave me but, Nothing happened

I tried again and the logo was moved to right which was not important for me because I will put a full width logo.

try this instead
#top-navigation .sf-menu li,#main-navigation .sf-menu li,#siteinfo { float:right !important; }

Done ?? ?? ??
