Thank you very much for your help, techaddict .
I had indeed changed the slug , but I could not change the permalink destination ;

I never thought “to flush” permalinks from trimmings .
Thanks again.

Thank you for your reply and sorry for staying so long .
I have no problem with the cache , because I delete regularly for testing .
In terms of my other plugins, it all begin automatically updated ( although I not use much ) .
For example : MB Metabox or contactform7 …
Anyway , I noticed today that the problem was resolved , since URE has updated itself.
It’s strange, because even if you made a change , I have not recovered , because I have not made any manual update …

Ok.
Au passage, si ?a t’intéresse, j’ai galéré aussi pour intégrer la même favicon que sur le reste de mon site (vu que le hook wp_head n’est pas pris en compte).
En fait, il faut le mettre en dur dans “index.php”.

Croro => Cela dit, si tu veux corriger le problème, il te suffit de désactiver le code que j’ai indiqué ci-dessus
