 * I tried this :
 * – Update to WP4
    – Update child theme – Update all plugins – Desactivate all 
   plugins – Desactivate child theme
 * The problem is still there.
 * In fact the only way to get rid of it is to change permalinks for default [http://www.mywebsite.com/?p=123](http://www.mywebsite.com/?p=123)
 * But as soon as I reactivate [http://www.mywebsite.com/%category%/](http://www.mywebsite.com/%category%/)
   the problem is here again.
 * My website is on a dedicated server, running for 1 year now without any problem
   under WP 3.6.1 (now WP4)
 * But on August 23th I decided to update more thant 300 jobs and to change permalinks
   for resumes (there are 4700 resumes) and the problem appears !
 * I also have two problems which are I think related :
 * – the server CPU usage sometimes goes up from 5% to 50% in one minute, when I
   publish a new post
 * – the server crashes about one time every week since late August.
 * Any idea?
 * thank you
 * John

 * A: Turn wp_debug off.
    B: If the overly robust **and intended only during development**
   _wp\_debug_ being off does not help (after flushing/clearing server cache), consult
   host.
