Hello. I would like to have a function that user can change his e-mail account password. I have configurated config.inc.php 'passowrd' in plugins. In the roundcube client there is the function to change password, but it isn't working. It wrotes me: "ERRORTITLE - Could not save new password". Where can be the problem? Thank you for your answer.
I'm not sure what you mean by that. Have you installed the ISPConfig Roundcube plugin? That has the function to change password, among others. Link to tutorial in my signature.
