Adjusting the maximum character limit for message
You can adjust the maximum length of the message text. The default is 500. To change it, follow these steps:
1. Log into your FTP site and edit wp-config.php
2. Edit wp-config.php and scroll to the end and add the following bit of code:
Scroll towards the bottom, and before the line that says “Happy blogging.” add this code ABOVE that line:
define( 'PWGC_MAX_MESSAGE_CHARACTERS', 500 ); /* That's all, stop editing! Happy blogging. */
3. Save the wp-config.php file and re-upload it to your server.
Let me know if that does the trick!
