 * Hello there,
 * I am running a website (wp 4.61 + classsipress 3.54). This morning I wanted to
   change something in the menu, and when I updated my menu I got this message :
 * Warning: strtolower() expects parameter 1 to be string, array given in /home/
   reseauacu/www/wp-includes/formatting.php on line 1870.
    This same message is 
   repeated 12 times.
 * the menu works though….
 * Don’t know when that problem began, it has been a while since I had changed the
   menu, and since it still works, I did not notice…
 * thanks for your help

 * If you temporarily switch to the Twenty Sixteen theme, do you encounter the same
   error when updating the menu?
