If you added the phrase like the instructions said, it should say
Read Private Messages
In the drop down at the top of the edit user page.

ok i will check

unless he didn't add the global phrase.

what global phrase?

here is what the modifed code looks like

$quicklinks = array_merge(
$quicklinks,
array(
"user.php?$session[sessionurl]do=emailpassword&email=" . urlencode(unhtmlspecialchars($user['email']))
=> $vbphrase['email_password_reminder_to_user'],
"../private.php?$session[sessionurl]do=newpm&userid=$userid"
=> $vbphrase['send_private_message_to_user'],
"usertools.php?$session[sessionurl]do=pmfolderstats&userid=$userid"
=> $vbphrase['private_message_statistics'],
"usertools.php?$session[sessionurl]do=removepms&userid=$userid"
=> $vbphrase['delete_all_users_private_messages'],
"usertools.php?$session[sessionurl]do=removesentpms&userid=$userid"
=> $vbphrase['delete_private_messages_sent_by_user'],
"usertools.php?$session[sessionurl]do=removesubs&userid=$userid"
=> $vbphrase['delete_subscriptions'],
"usertools.php?$session[sessionurl]do=doips&userid=$userid"
=> $vbphrase['view_ip_addresses'],
"../member.php?$session[sessionurl]do=getinfo&userid=$userid"
=> $vbphrase['view_profile'],
"../search.php?$session[sessionurl]do=finduser&userid=$userid"
=> $vbphrase['find_posts_by_user'],
"../$modcpdir/banning.php?$session[sessionurl]do=banuser&userid=$userid"
=> $vbphrase['ban_user'],
"user.php?$session[sessionurl]do=remove&userid=$userid"
=> $vbphrase['delete_user'],
"pm.php?$session[sessionurl]userid=$userid"
=> $vbphrase['read_pm_user'],
)
);

if (intval($user['adminpermissions']) & CANCONTROLPANEL AND in_array($bbuserinfo['userid'], preg_split('#\s*,\s*#s', $superadministrators, -1, PREG_SPLIT_NO_EMPTY)))
{
$quicklinks["adminpermissions.php?$session[sessionurl]do=edit&userid=$userid"] = $vbphrase['edit_administrator_permissions'];
}

$userfield = $DB_site->query_first("SELECT * FROM " . TABLE_PREFIX . "userfield WHERE userid = $userid");

If you look at the bottom of the instructions above, it says the following
and you need to add your code above in tag's to prevent unlicensed users from reading it.

thats the code?

could u send me what the code should look like

so what you want to do now is in the Laguages & Phrases section, click on Phrase manager, then Click add new phrase, then in the drop down box you want to select control panel global, varname will be read_pm_user, and the test will be Read Private Messages or whatever you'd like to call the variable.

ok i wil ltry

you asked, so the code after you make the file edit in admincp/user.php should look like this.

note that nothing will show up untill you add the Control Panel Global Phrase.

ok let me just forward this to my admin see if he got it

thanx everyone ive now done it
big thanx to you all sorry for being a pest
