 * Hello,
    after the migrations I often (or maybe always) get this error:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/serigrafiaweb/public_html/wp-config.php:1) in /home/serigrafiaweb/public_html/
   wp-includes/pluggable.php on line 1179
 * usually, I solve it, changing the folders wp-admin and wp-include with original
   folders of wordpress.
 * This time I didn’t solved it so.
 * There aren’t spaces on line 1 of wp-config.php, I already tried to deactiving
   all plugins and themes, I also tried to install clear wordpress,and I import 
   the database, I get same error… so maybe the error it’s for something in database…
 * Can you help me?
 * Thanks a lot!

 * Please review that you may not ‘see’ the extra space or extra line or BOM in 
   some editors. I use [NotePad++](https://notepad-plus-plus.org/) _and turn hidden
   characters_ on **before uploading** a wp-config.php file.
 * It would be great, if instead of positioning folks to a page that does not actually
   help, that mods actually answered based on their experience.
 * This **Plain Text Editor** will show you the BOM or white space or extra line.
