Horde -No browseable address books

Edit the file:

/usr/local/cpanel/base/horde/turba/config/sources.php

on the server with your favorite command line editor. Look for a line of code that reads like:

'public' => false,
'readonly' => false,
'admin' => array(),
'export' => true

Should be around line 132 I believe. Add 'browse' => true, to this section of code, so that it reads as:

'public' => false,
'readonly' => false,
'admin' => array(),
'browse' => true,
'export' => true

Then just save the file and log back into Horde.
