Ok I didn’t put the .htaccess on the root and in the WordPress folder, sorry for the time spent on my project, and thank you moshu.
Structure: /%year%/%monthnum%/Úy%/%postname%/
Structure: /archives/%post_id%
I updated the new .htaccess file with the content in options-permalink.php and there is still no difference.
And how can I solve this problem ?
I deleted the .htacces in the /root folder, but that doesn’t change at all.
