Excuse my inexperience but I tried changing the “permaliens” (this is the name in french) to the “numeric” (/archives/123) classification and everything seems to function now. Example : http://taraquebec.org/Wordpress/archives/category/analyses/analyses-sociales/
Remains only the problem of the accentuated letter (é, à, etc.) in french to include, if possible, in the program code.
