Well again it seems it partially works.
When I go to the posting section of the control panel the text field is Right-to-Left but apparently it converted to some kind of plain text editor where I must put the whole HTML code for the blog post. As you see the toolbars and menus are gone too.(I accidentaly took a screenshot of an English written page, but I checked an I can write a Right-to-Left text in the field)
Again thank you for helping me.
