Still getting similar result after code modification...
I still have similar incoming message as before even though I have added your suggested code in Center.php in the $removeBegins = array() and make a new contactus.php using CSSFB.
I am attaching my contactus.php rename to contactus.txt, Center.php rename to Center.txt code and incoming images for you to see.
Hopefully you can find my errors, and let me know what to do.
Actually during creation contactus.php I enter manually where to go after submit button pressed but in fact it still showing the same contactus.php page again!
Thanks, I am looking forward to hear from you soon.
