The Permalink Editor worked great for what I needed for my website.
Only problem is that since is a 2 languages (EN, FR) website with qTranslate installed, the "customized" permalinks for the secondary language (FR) return a 404 page.
I really need to fix this because I can't have the French version of those pages broken.
Thanks in advance to anybody who will help me out with this.
I can provide the URLs of the pages if needed.
