Roundcubemail web interface problem

[Jonathan Bustillos]

Hello everybody. I entered to the mail account of one of my users through roundcubemail and after changing the interface theme for the named "Kolab" in blank, my web browser tells me with a message:

And I can not back to roundcubemail login interface any more. What I need to do for restablish it please? I am using Kolab in a Debian Jessie server. Thanks.
