Adv Guestbook 2.3.1: Modifying messages in lang/*.php files

Hello. Congratulations on an outstanding application!

I have a question regarding customization of various text throughout the Advanced Guestbook. I'm trying to modify text in lang/english.php. After I save the changes and upload it to the server however, ALL messages found in this file do display at all in the guestbook, neither the original or modified text. The result is just blank space where text should be, and the scattered icons.

How can I make changes to the text in "english.php" and have them save and display properly? What am I missing?

Thanks for a great utility!

Best regards,

Chris Weil
