# Possible errors after permalinks modifications

 * My current WP configuration
    • PHP / MySQL version: less than 5.6 • Theme used:
   Viewport • Extensions: Askimet, AMP, Google Adsense, GADWP, Image Widget, Polylang,
   Publish to Apple News, Redirection, Simple Light Box, WP Rocket, Yoast • Name
   of the host: Infomaniak • Website address: yesicannes.com and yesicannes.com/
   fr
 * Hi there,
 * Two changes in permalinks resulted in a chaos in the URLs, causing countless 
   errors 404. Someone from WP.org support suggested the 404’s could come from URLs
   rewriting by Polylang. Would someone please be so kind as to take some of his
   precious time to see if my issue has something to do with Polylang?
 * YesICannes is a web magazine in 2 languages: yesicannes.com and yesicannes.com/
   fr. Our articles are indexed in GoogleNews, so the articles’ URLs must include
   some numbers.
 * Until recently, my permalinks were: yesicannes.com/%postname%
    To add the numbers
   desired by Google, I used to preview the post and then manually added the generated“
   post id”, separated from the title of the article by a “-“.
 * Then, I thought to do this insertion automatically by modifying the permalinks
   with the following form: yesicannes.com/%postname%/%post_id%/.
    Surprisingly,
   the links were displaying: yesicannes.com/postname/post_id/post_id/ with twice
   the number automatically inserted (!?) But I did not have an alert from Google.
 * But I thought that with a “/” as a separator, it did not look like the URLs created
   so far, and I changed the permalinks a second time from “/” to “-” to get yesicannes.
   com/postname%-% post_id%/
 * I then started receiving calls from visitors who had 404 errors in the latest
   published reports and Goolge sent me a mail talking about augmented 404 errors
   on [http://yesicannes.com/](http://yesicannes.com/) and [http://yesicannes.com/fr/](http://yesicannes.com/fr/),(
   type message [WNC-658800]).
 * Well, I understand that going from “/” to “_” can create 404 errors, and I realize
   my mistake. But the problem is more disturbing: the 404 errors display this kind
   of link, i.e. whereas the normal URL is: [http://yesicannes.com/fr/mouratoglou-tennis-academy-sophia-antipolis-33009](http://yesicannes.com/fr/mouratoglou-tennis-academy-sophia-antipolis-33009)),
   the bad link is:
 * [http://yesicannes.com/fr/mouratoglou-tennis-academy-sophia-antipolis-33009/33009/mouratoglou-tennis-academy-inauguration-10/](http://yesicannes.com/fr/mouratoglou-tennis-academy-sophia-antipolis-33009/33009/mouratoglou-tennis-academy-inauguration-10/)
 * Another example of error 404: (whereas [http://yesicannes.com/fr/mouans-sartoux-miel-ciel-provence-36831/](http://yesicannes.com/fr/mouans-sartoux-miel-ciel-provence-36831/)
   is good)
 * [http://yesicannes.com/fr/mouans-sartoux-miel-ciel-provence-36831/36831/fete-du-miel-mouans-sartoux-2017-12/](http://yesicannes.com/fr/mouans-sartoux-miel-ciel-provence-36831/36831/fete-du-miel-mouans-sartoux-2017-12/)
 * The number is repeated with some kind of replication of the name of the post…
   Would anyone have an idea id Polylang URl rewriting has to do with this embarrassing
   situation?
 * Thank you in advance for your help.

 * Hi everybody,
 * How come I never get an answer on this Polylang support forum when I post an 
   issue?
 * Is this too difficult a problem for you experts?
 * Please let me know your mind.

 * I understand your frustration, and yet, bear in mind that it is free plugin and
   people are volunteering on this 🙂
