[HowTo] Password Changer Roundcube 0.3 Stable

[Dylan]

Hi!

I download roundcube 0.3.1, upload it to the tools dir, unzip it to cube dir.

I change the config files (roundcube work well done, send-recive etc), but the password changer not.

The debugger write to into the log file:
PHP Fatal error: Call to undefined function send_request() in /var/www/webui/gui/tools/webmail/plugins/ispcp_pw_changer/drivers/sql.php on line 40

What can I do now?
The database rights ok, in admin panel e-mail status is: "under change".
When I modify on admin panel another email address (change anything), after it, all OK, and the new password is usable.

I try to change the line 39, but then it says into the log:
PHP Warning: require(/../../../../include/ispcp-functions.php) [<a href='function.require'>function.require</a>]: failed to open stream: No such file or directory in /var/www/webui/gui/tools/webmail/plugins/ispcp_pw_changer/drivers/sql.php on line 39

So it can open the ispcp-functions.php with the right line, but send_request() function not work. Why? It's on the file.
I use Ispcp 1.0.4 now.

Sorry for my English. I hope you understand my problem.
