Everyone in 'Unknown Location'?? PLEASE READ

[MattRogowski]

OK, within the past 48 hours 4 people have said they have all their users showing in an 'Unknown Location'. I'm making this into a sticky to pool together what information people have given and give things people to try, because if past experience is anything to go by, more and more people will have this issue.

Michael83 has posted a possible fix, can you read this quote, and see if it works for you:

PHP Code:

switch($filename) 


Above add:

PHP Code:

$filename = str_replace("/", "", $split_loc[0]);

It doesn't seem that there's a plugin that's in all of these lists, so I'm not sure if this is caused by a plugin or not.


If you have just upgraded to 1.4.5 and are experiencing this, please make sure you have all the 1.4.5 files and that you upgraded properly. Also try to download a fresh copy of ./online.php and ./inc/functions_online.php from the full 1.4.5 package and from the changed files package and see if either of these fixes it.

Also, it would be good to try and keep further reports of this to this thread because, as I said before, I can see lots of other people reporting this over time.

Hi everyone,

This is caused from a bug in the MultiByte extension provided on some hosts with PHP . The mb_substr function is performing incorrectly on some versions of the package.

To resolve this issue permanently please talk to your host to upgrade the MultiByte to the latest version available.

To resolve this issue temporarily, or if your host is unable to upgrade, please apply the follow fix:

In inc/functions_online.php find:

PHP Code:

$filename = my_substr($split_loc[0], -my_strpos(strrev($split_loc[0]), "/")); 


replace with

PHP Code:

$filename = substr($split_loc[0], -my_strpos(strrev($split_loc[0]), "/")); 


Please note, the temporary patch will not be applied to the official MyBB download or considered a bug in MyBB or fixed in any future maintenance release. It is a bug in the MultiByte PHP extension. We strongly encourage our users to keep their servers up-to-date, or otherwise encourage their hosts to keep their servers up-to-date.

Thank you for your continued understand and cooperation,
MyBB Group

Wow bro thank you very much.

For those who don't know how to install MultiByte extension, run this in shell

Code:

yum install php-mbstring

Ok, I send a message to HostGator (my host) about the MultiByte extension. This is what they send back:

The section of code they are referring you to determines the user's location within the forum - that is, the page they are viewing and not their physical location.
Even after applying this "fix" the profiles continue to show that everyone is located in Liverpool. This particular extension is compiled into PHP and we are running the latest version of PHP on your server, meaning that this is the most up-to-date version of the MultiByte extension as well. Please check with MyBB and see if they can provide you with a more relative answer to this issue.

My forum is TF2Forum(.com) . Note: I guess I got a slightly different problem because with me all the people are from ''Liverpool'' and not ''Unknown Location''. Perhaps I have a different problem?

PS: No, not all my members are from Liverpool or filled in that they are from Liverpool .

[MattRogowski]

Is this even the same issue?? How has living in Liverpool got anything to do with everybody showing as being in an Unknown Location on the WOL?? This is nothing to do with filling in a custom profile field...

It looks like your host has no idea what they are talking about.
