Illegal string offset - please help what is this?

Hi guys,

All of a sudden I started getting this error on my forums when I try to view users online

http://store.img-share.eu/f_pngt7sR5jz.png

Any help will be greatly appreciated. :confused::(

Do you get that same error with your mods disabled?

Sadly yes.

Errors are suppressed in 4.2.2 this one appeared suddently and won't go away.

What is on line 516 in that file for you?

I haven't checked. The error message suddenly disappeared.

Thanks for your time and reply ozzy, you are doing a wonderful job here for the community.

I have no idea how this error message appears then suddenly disappears, I haven't changed anything and posted this thread out of desperation...

I hope Paul M reads this thread!!!

Thanks, I try and help out where I can. :)

What I would do is if it comes up again, see if there is any similarity's / differences when it appears, versus when it don't appear.

It has started again, this time shows on two lines!

Horrible. I don't know what to do. It comes up and goes in random manner.

:(

We need to know whats on those lines.

From the file:

PHP Code:


		
			
            case 'pm':
                $userinfo['action'] = $vbphrase['private_messaging'];
                if ($vbulletin->userinfo['permissions']['wolpermissions'] & $vbulletin->bf_ugp_wolpermissions['canwhosonlinefull'])
                {
                    if ($seeuserid)
                    {
                        $userinfo['where'] = '<a href="' . fetch_seo_url('member', array('userid' => $seeuserid, 'username' => $wol_user["$seeuserid"]['username'])) . "\">$username</a>";
                    }
                    if ($userinfo['values']['do'] == 'newpm' OR $userinfo['values']['do'] == 'insertpm' OR $userinfo['values']['do'] == 'newmessage')
                    {
                        $userinfo['action'] = $vbphrase['creating_private_message'];
                    }
                    else if ($userinfo['values']['do'] == 'editfolders' OR $userinfo['action']['do'] == 'updatefolders')
                    {
                        $userinfo['action'] = $vbphrase['modifying_private_message_folders'];
                    }
                    else if ($userinfo['values']['do'] == 'trackpm' OR $userinfo['values']['do'] == 'deletepmreceipt')
                    {
                        $userinfo['action'] = $vbphrase['tracking_private_messages'];
                    }
                    else if ($userinfo['values']['do'] == 'showpm')
                    {
                        $userinfo['action'] = $vbphrase['viewing_private_message'];
                    }
                    else if ($userinfo['values']['do'] == 'downloadpm')
                    {
                        $userinfo['action'] = $vbphrase['downloading_private_messages'];
                    }

                }

with line 516 being:

PHP Code:


		
			
                    else if ($userinfo['values']['do'] == 'editfolders' OR $userinfo['action']['do'] == 'updatefolders')

The entire snippet starting at 516 to finish is:

PHP Code:


		
			
                    else if ($userinfo['values']['do'] == 'editfolders' OR $userinfo['action']['do'] == 'updatefolders')
                    {
                        $userinfo['action'] = $vbphrase['modifying_private_message_folders'];
                    }

And you said w/ plugins disabled it still persist so can't be a little pm preview plugin or similar causing it must be issue regarding 4.2.2 then.

Thanks for your replies. As I said it comes and goes, some days it hits us real bad otherwise we are business as usual.

This is most likely a 'mod/plugin' that is causing your trouble or other sites would have reported it. I would be looking at what commands were being performed in the logs prior to this being triggered. The first step in solving a problem like this is to be able to repeat the condition.

I was going to suggest a method to trap the error and use xdebug to trace through it once you could repeat the condition, but that method might be too advanced of a step for you -- after reading through you threads. If I am wrong please let me know.

Since your a production board, disable any PM mods you are using for now and see if the problem goes away. It would be helpful if you posted what you tried. :)

Thanks for your reply tbworld.

I managed to replicate the error - it only happens when at least one user is viewing their pms.

There are similar complaints posted on other boards about the same issue

Please suggest your method to "trap" the error.

I put $userinfo['values']['do'] == 'updatefolders' instead of $userinfo['action']['do'] == 'updatefolders' and the error message no longer shows.

Thanks to everyone who responded.

Thanks for sending the data, and the reference, it was extremely helpful. If I can simulate this error, I will also report it vbulletin's JIRA.

Good Job! I believe your change is correct, I had to ponder why this did not show in earlier versions.
