 * I change the server recently for the first time, reading a manuscript carefully.
   
   after that, a warning comment is displayed when I move the mouse to the “posts”
   on the left column.(I don’t know it correctly as I am using a Japanese version…
   sorry!) The error says: Warning: Cannot modify header information- headers already
   sent by (output started at/home/USERNAME/SITE ADDRESS/public_html/wp-includes/
   formatting.php:5078)in/home/USERNAME/SITE ADDRESS/public_html/wp-includes/rest-
   api.php online 511
 * the corresponding php are followed:

   at a src version of this file, you’ll see an “include” * statement below. This

 * Hi,
    1- I would suggest to upload the all files of WordPress except the /wp-content/
   directory, wp-config.php and htaccess files.
 * 2- Try deactivating all plugins. If that resolves the issue, reactivate
    each
   one individually until you find the cause.
 * Thanks
    Mohammad
