Hi everyone, this is the first time i write on a forum but i need help with roundcube.
One of my costumers has several email account on his cpanel account, and the mail server is runnung correctly.
I can open with browser every single email account with roundcube and horde, but if i try to open the default mail account ( and so see every address ) roundcube gives me error 500. Instead horde is working fine, but they prefer to use roundcube.
I have tryed to open /usr/local/cpanel/logs/error_log but there is nothing on this error.
Can someone help me?

P.S. Sorry for my bad english
