I have enabled this plugin in my roundcube main config file.
I have also updated the plugin's config.inc.php file:
// Driver - 'file' or 'sql'
$rcmail_config['squirrelmail_driver'] = 'file';
// full path to the squirrelmail data directory
$rcmail_config['squirrelmail_data_dir'] = '/var/lib/roundcube/squirrel';
$rcmail_config['squirrelmail_data_dir_hash_level'] = 0;
That directory has all the .abook and .prefs files from the old squirrelmail setup. The files are readable for the webserver.
However, when going to the address book in roundcube, I'm not seeing the extra import button that should appear.
What else can I do to troubleshoot this? I'm running the latest debian packages for roundcube (0.7.2-9+deb7u1).
Thanks!
