I am using Roundcube without any problems, so you probably want to provide details of your error messages so people can help you.

Not sure if you are having the same problem I had or not, but after having the same message and looking at my logs I found the issue was with Dovecot. I did an update of the system and something with Dovecot changed. Namespace issues. Here is what I did:

edit /etc/dovecot/dovecot.conf using vim/vi/nano (whatever you prefer)

Add the following:
namespace inbox {
inbox = yes
}

I can't say for sure this is the same problem you are having, but if you check your dovecot.log (/var/logs/dovecot.log) and you see the below error messages then try out that fix.

imap([email protected]): Error: user [email protected]: Initialization failed: namespace configuration error: inbox=yes namespace missing

I faced the same issue on CentOS 7 + VESTA and I confirm that the solution provided by Thantis works :-)

BTW, you might want to make this change to /etc/dovecot/conf.d/10-mail.conf where namespaces are supposed o be defined.
