Hello. i'm new in here and I've already searched in different topics about this issue and I haven't been able to find a solution yet.
I've installed the latest Roundcube Webmail and I'm trying to install the Password plugin (the one that lets users change their own password) and I haven't been able to do so successfully. The option is displayed in the Settings section but when I try to modify the password, it sends me to a blank page and the password is not changed.
I followed all the steps mentioned in the Readme file and some info here trying to install the cpanel driver: http://www.roundcubeforum.net/index.php?topic=9677.0 as well as everything I've been able to find on the internet.
Can anyone please help me? What is it that I should do? I'd really appreciate it.
EDIT: Seems like the log is as follows:
