Thanks go to Nemesis02 for updating the cPanel addon to work with roundcube0.2stable without which this update wouldn't of been possible. Not from me anyway!!
And of course many thanks to BoerbooM for the original plugin
OK, so here's what I did.
I used Nemesis02's README to make the file alterations too:
index.php
program/js/app.js
program/localization/en_US/labels.inc
program/localization/en_US/messages.inc
program/localization/en_GB/labels.inc
program/localization/en_GB/messages.inc
skins/default/includes/settingstab.html
I also kept his password.html and password.inc, replacing the
rcube_save_password function with the equivalent
rcmail_save_passwd from BoerbooM's passwd.inc, then changed the code to use the encrypt_password function from in the new password.inc.
The httpsocket.php file from BoerbooM's original plugin hasn't changed.
I'll post the patch to the downloads section, follow the README for installation instructions
GOOD LUCK!!!
