# Unable to update posts

 * My blog (oreilletendue.com) runs on WordPress 4.6.1, with the Twenty Sixteen 
   theme.
 * Until yesterday, everything worked fine. Since this morning, I can create new
   posts, but I am unable to update older posts.
 * When I try to update an older post, I’m sent to the following page “Oups ! Cette
   page est introuvable.” (Oups! No such page.)
 * I’ve tried deactivating all plugins, but to no avail. The problem remains the
   same.
 * Any clue?

 * Judging by the people that “fixed” this in the last couple of hours this seems
   to involve a new mod_security rule (on the host) throwing a fit when a < character
   is involved. Host removing said rule fixes the issue.

 * Thanks for the reply. I’m afraid this is way beyond my technical skills. You 
   know of any place where this procedure is explained in detail?

 * I am in the same boat, and tried all the normal 404 error fixes. It seems to 
   have to do with formatting any text in the posts.

 * I solved the problem by talking to host. It was about mod_security rule.
