WYSIWYG not showing up when language was changed to arabic | IE & FF

[arpiyem]

hi,

we have added an Arabic language in the Language Manager and translated most of the texts to arabic and orientation is RTL. all is good so far, except for the WYSIWYG editor which is not showing up on IE and Firefox when changed to Arabic language. someone on my team told me that it is working fine using Chrome though. i am referring to all the WYSIWYG editors which we can see in the creation of threads/topics or replying to a thread.

the link to our forum is
http://72.55.165.41//forums.dev/

please switch to english language so you can better understand the site. (that's what i'm doing )

i hope someone could help us because this is a show stopper on our end.

thanks in advance.
