FLEXIcontent - Content Lists Filtering: Wrong URL when displaying results.

After deleting all menu item linked to the category and recreating them, the problem was fix. 

I have to put this project on the side for now. I did not recreate the English part of the site. If the problem reappear, I'll try my best to document my actions and hopefully understand what happen.

Thank you for your help.

Thanks for returns !

I have find a solution. Here it is in case someone need it. (I hope it's clear enough)

At first I only had one category for french and English. (The language was set to ALL). The reason for that is because I wanted the users to see all the items, no matter the language. 

My "one category for two languages" technique was the problem. The solution was to create 2 categories. One french and one English. and then set those two categories as secondary for each articles (those article's language is set to all) . Then I made two different Menu item. One in french, the other in English. Each one point to the category with there respective language.

Now that I have two categories, I do not have a problem with Flexi not knowing where he should take me. And since all the articles are set with the two categories, they still show up in both language.

thanks for sharing solution
