What vBulletin version are you using?

You may have to update your vBulletin version to a version that supports PHP 5.6+ in order to get rid of these errors. Unless of course you don't mind making manual modifications to the /includes/functions.php file.

using:
vBulletin® v3.8.11, Copyright ©2000-2017, vBulletin Solutions Inc.

I think this version supportes php 5.6+

First of all, those line numbers dont match up with the default functions.php for 3.8.11, which makes me wonder if you have the correct files uploaded.

Secondly, they are due to invalid data being passed to core functions, which indicates you have an issue elsewhere, in a modification maybe.

thanks for your reply
here is what my functions.php have on mentioned lines
maybe can help find problem:

[10-Jun-2017 20:16:42 UTC] PHP Warning: Illegal string offset 'usergroupid' in /home/user/public_html/includes/functions.php on line 383

$membergroups[] = $user['usergroupid'];


[10-Jun-2017 20:16:42 UTC] PHP Warning: Illegal string offset 'usergroupid' in /home/user/public_html/includes/functions.php on line 449

if ($userinfo['usergroupid'] == $usergroupid OR in_array($usergroupid, $user_memberships["$userinfo[userid]"]))


[10-Jun-2017 20:16:42 UTC] PHP Warning: Illegal string offset 'userid' in /home/user/public_html/includes/functions.php on line 440

if (!is_array($user_memberships["$userinfo[userid]"]) OR !$cache)

I already told you what the actual problem is :)
Which as I also said, indicates you have an issue elsewhere, probably in a modification thats calling the functions.

ok thanks, ill check modifications
and u have same idea on errors below?

You need to find where the split() function is being used and replace those with the explode() function.

In line 100 of misc.php, you will likely find "=&" being used...replace that with just "=".

its what the misc.php line 100 contains:
($hook = vBulletinHook::fetch_hook('misc_start')) ? eval($hook) : false;

here is the only split that i have found on global.php
$val = preg_split('#\n#', $vbulletin->GPC['vbulletin_collapse'], -1, PREG_SPLIT_NO_EMPTY);

please advise how to fix the functions

Yes, I was mistaken...there is code being evaluated at that hook with the deprecated code in it. Try to find the "=&" operator being used in a plugin hooked at "misc_start".

The deprecated functions won't be in the "global.pho" file itself, but rather in code executed at the plugin hook locations specified at those given lines.
