Error in Horde(Webmail)

While trying to browse webmail using webmail.domainname.com it shows following error:
Warning: main(PEAR.php) [function.main]: failed to open stream: No such file or directory in D:\I
netpub\vhosts\webmail\horde\lib\core.php on line 26

Warning: main() [function.include]: Failed opening 'PEAR.php' for inclusion (include_path='D:\Ine
tpub\vhosts\webmail\horde\lib

;.;./includes;./pear') in D:\Inetpub\vhosts\webmail\horde\lib\core.php on line 26

Open core.php file of horde: C:\Inetpub\vhosts\webmail\horde\lib\webmail\horde\lib\core.php

change this:
ini_set('include_path', dirname(__FILE__) . PATH_SEPARATOR . ini_get('include_path'));

To:
ini_set('include_path', 'C:/Inetpub/vhosts/webmail/horde/lib' . PATH_SEPARATOR . 'C:/Inetpub/vhosts/webmail' . PATH_SEPARATOR . 'C:/Inetpub/vhosts/webmail/horde/pear' .PATH_SEPARATOR . ini_get('include_path'));

The password changing option in horde webmail is not working

When a user uses the "Password" button/icon in webmail, it shows them just the first part of thei
r username instead of the full emailid@domainName address as their username. So, changing their p
assword doesn't work.

Edit the file /etc/psa-horde/passwd/conf.php. This path /etc/psa-horde will change according to t
he plesk horde setting.

Find the line that says:
$conf['hooks']['default_username'] = false;

Modfiy the code line to
$conf['hooks']['default_username'] = true;

Now, create a new file hooks.php

like /etc/psa-horde/horde/hooks.php (the path /etc/psa-horde will change according to the situati
on)

In this file, paste the following:
/**
* Horde Hooks configuration file.
**/

if (!function_exists('_passwd_hook_default_username')) {
function _passwd_hook_default_username($userid)
{
return $userid;
}
}
/** DO NOT PLACE A ?> AT THE END OF THIS FILE **/

Most probably, you can find the file hook.php in the corresponding path with the above code comme
nted. Uncomment the line.

Now users can use the Password button in Webmail, and it will work correctly.
