Hi - since I migrated from rcm 0.5 to 0.6, my inbox is greyed out. I cannot click on the inbox anymore in the folders list, but have to use the e-mail button in the top menu bar. Any idea what may have triggered this behavior?
I suppose your IMAP server sends some wrong response to LSUB command. Enable imap_debug in Roundcube and provide the log from the moment when you log in until LSUB.
Thanks. The hint that this might be the issue helped. I had configured (since ages) imap_ns_personal as "INBOX". Adding the dot at the end (i.e. "INBOX.") helped. Seems that something changed there since 0.5 which I missed.
