I found the solution for the "Internal Server Error" after logging into roundcube after the upgrade:
disable the spoof check
Edit the file:
nano /usr/local/cwpsrv/var/services/roundcube/program/lib/Roundcube/rcube_spoofchecker.phpAround line 50, you'll see something like:
PHP// Spoofchecker is part of ext-intl (requires ICU >= 4.2)
$checker = new Spoofchecker();Insert this line right before the $checker = ... line:
return false;So it looks like:
return false;
// Spoofchecker is part of ext-intl (requires ICU >= 4.2)
$checker = new Spoofchecker();Save and exit.
Then restart:
sh /scripts/restart_cwpsrv
