Roundcube: connection to storage server failed

it may be that the dovecot index files are for an older version of dovecot, and don't work full with the new version.

To resolve that issue, simply delete all dovecot index files, and dovecot will re-create them when it notices they're missing.

You should test this on one User first, before doing it on all Users.

Also, backup the dovecot* files of the test User first (shouldn't be required, but not a bad thing to do)

Fix 

====

cd /home

/etc/init.d/dovecot stop

rm -f */imap/*/*/Maildir/dovecot*

rm -f */imap/*/*/Maildir/.*/dovecot*

rm -f */Maildir/dovecot*

rm -f */Maildir/.*/dovecot*

/etc/init.d/dovecot restart

====

Dovecot will recreate the dovecot* files once the User logs in.

Got blank page when accessing RVSkin.

1. Please force update using this command.

rm -f /usr/local/cpanel/Cpanel/rvversion
perl /root/rvadmin/auto_rvskin.pl

2. Go to root WHM >> Server Configuration >> Tweak Settings >> System >> Accounts that can access a cPanel user account, and mark at "Root, Account-Owner, and cPanel User"

 If still not work, please SSH to your server and run following command.

cd /usr/lib/perl5/site_perl
ln -s 5.8.8 5.6.2

Cool Fix !!! :D
