[SM-USERS] Error page after changing user passwords

[Ozgur K. <ozg...@in...>]

Hello.

I've SquirrelMail version 1.4.20 with the plugin change_sql_pass 3.3-1.2. (PHP 5.2.13 with Suhosin-Patch 0.9.7 @ Apache 1.3.29 @ OpenBSD 4.6)

I can successfully change users passwords but after I submit the "Change Password" form, it redirects me to a page with the following error;
"ERROR: This page request could not be verified and appears to have expired."

How may I change this with something like 'Password changed successfully!'?

Many thanks,
Best Regards.
