You did not do the other edit below that post which is edit for vbsupport.php in the admincp folder. See post https://vborg.vbsupport.ru/showpost....&postcount=478.
Also in the main vbsupport.php (one not in admincp folder)I forgot another edit I think

Find :

// unserialize the datastore
$vbulletin->vbs_category = unserialize($vbulletin->vbs_category);
$vbulletin->vbs_admin = unserialize($vbulletin->vbs_admin);

// check if the user is an admin
$show['useradmin'] = false;
if (vbsupport_can_moderate('canadminsupport'))
{

Change too:

// unserialize the datastore
$vbulletin->datastore->do_db_fetch("'vbs_category'");
$vbulletin->vbs_category = unserialize($vbulletin->vbs_category);
$vbulletin->datastore->do_db_fetch("'vbs_admin'");
$vbulletin->vbs_admin = unserialize($vbulletin->vbs_admin);

// check if the user is an admin
$show['useradmin'] = false;
if (vbsupport_can_moderate('canadminsupport'))
{

also for pms to work:
find in vbsupport.php:

 // build the $emailids
 
    $pmids = explode(',', $vbulletin->vbs_category["$categoryid"]['adminpmusers']);
    $emailids = explode(',', $vbulletin->vbs_category["$categoryid"]['adminemailusers']);

    // check for email notifications
    if (is_array($emailids) && is_array($pmids))
    {
      // process add admins

      foreach($vbulletin->vbs_admin AS $userid => $user)
      {

Change too:

 // build the $emailids
    $vbulletin->datastore->do_db_fetch("'vbs_category'");
    $pmids = explode(',', $vbulletin->vbs_category["$categoryid"]['adminpmusers']);
    $emailids = explode(',', $vbulletin->vbs_category["$categoryid"]['adminemailusers']);

    // check for email notifications
    if (is_array($emailids) && is_array($pmids))
    {
      // process add admins
      $vbulletin->datastore->do_db_fetch("'vbs_admin'");
      foreach($vbulletin->vbs_admin AS $userid => $user)
      {

Quaterbore posted a phrase add which must be done for pms regards to a support ticket being deleted by another admin and then clicking on the link in the PM that was sent by that ticket will cause an error since no phrase exists to handle this particular case.
