hi,
i think that i found the problem, but i dont know how to fix it.

when i am adding a category in english its work fine, when i am adding in hebrew, it fail, i am getting this:

Notice
Saving category 0 failed: Cannot save category: Alias '' has already been taken.

important! the problem that it isnt make an alias automatic, if i write an hebrew category name and i am adding a alias in english it create the category, i need that it will produce an automatic alias, even in numbers as joomla does.
