No administrative CSS for arabic language I have a multilingual website with English, French, and Arabic; I updated from Drupal 7.22 to 7.23 and I found that I don't have the CSS for the homepage in Arabic, as the image below.



Why is it happening? How can I fix this?

Notes

I'm aggregating and using Advanced CSS/JS Aggregation advagg.  I'm using Boost module.
By default, many themes have a separate RTL template or CSS. Depending on what theme you are using, you may have to create RTL CSS or change the behavior of which CSS files it's looking for. Try searching for a *-rtl.css file (where * is some name that comes before the suffix.)
