if I search (in a pretty big folder) for a string I get an error in about 3 seconds. I saw this error with an instruction to change default_socket_timeout - that is now set to 240!
error still happens.
any ideas?
Roundcube uses the search functions on IMAP server. The IMAP server is timing out when you perform a search so you need to look at the IMAP logs to find the reason for the problem.
