I just read the solution to my problem in http://wordpress.org/support/topic/128032
thank you for replying!
The problem was that I wanted the prefix for Categories to be
/ instead of
/category/, so iamParah said that by putting
/. my problem would be solved. and it is, almost.
know I have another problem, the subcategories don't work. I think it might be because the Post Permalinks are
/%category%/%post%/ so maybe it is conflicting? Is there a way to fix this?
I wanted this to use the categories as sections, so each post is asigned to only one category...
