 * Hello, After reading lots about this message, I have learnt that I am required
   to change some coding in the relevant file but I am not sure what I am meant 
   to be changing. I have the following code:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/peekaboo1949/public_html/www.llanddewcc.org/wp-content/plugins/drop-
   shadow-boxes/freemius/includes/entities/class-fs-payment.php:1) in /home/peekaboo1949/
   public_html/www.llanddewcc.org/wp-login.php on line 394
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/peekaboo1949/public_html/www.llanddewcc.org/wp-content/plugins/drop-
   shadow-boxes/freemius/includes/entities/class-fs-payment.php:1) in /home/peekaboo1949/
   public_html/www.llanddewcc.org/wp-login.php on line 407
 * In another topic I was advised that I needed to change the following file: plugins/
   drop-shadow-boxes/freemius/includes/entities/class-fs-payment.php on line 1.
 * Can anyone guide me on this as I am not sure what to change.
 * Many Thanks
 * Charlotte

 * Is there no support for this issue. I am not sure if I am meant to be deleting
   something in the FTP or the wp-login.php.
 * I would be grateful for any assistance.
