Database error

[bosanci28]

Hello,

I am getting some emails with "Database error" message from my forum and not really sure why!

This is what i get:

>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Database error in vBulletin 4.2.2:

Invalid SQL:
SELECT location, badlocation FROM session WHERE userid = n AND lastactivity > 0 ORDER BY lastactivity DESC LIMIT 1;

MySQL Error : Unknown column 'n' in 'where clause'

Ip address is changed all the time,in every email ! so i guess there are from different people.

Thank for any advice on this.

How can you have a userid of "n"? "n" is a letter, not a number and the userid must be a number.

[bosanci28]

Hmm, i am not sure whats with the "n" in there as is not in the user groups.

I would guess it is a "Who's Online" related query...have you recently installed any new add-ons that report user location or activity of any kind?

The Script part of the error can you post it we need to see what script caused the error

[bosanci28]

See attached , i did installed quite few mods as my forum is new and getting started.
But i suspect maybe is the mod: "member tracking" but not sure.

My guess is that the n should be a variable $n or something along that line. Depends on the script that is calling this Query.

Disable plugins via config if this fixes the problem enable plugins again via config, then disable one plugin at a time until you find the problem one

To temporarily disable the plugin system, edit includes/config.php and add this line right under <?php

PHP Code:

define('DISABLE_HOOKS', true); 


To enable plugins again just comment out the line

PHP Code:

//define('DISABLE_HOOKS', true); 


Use notepad++ to edit any files

Thank you to all for helping!

Okay, So i have disabled , that plugin "Member Tracking" and today i still got about 6 emails with the same message .

So i have i disabled all plugins via config.php and now will give it a day or two to see if the error
comes back.

Thank you.

If you get the error again, can you please include the Script and Referrer so we can see what script and page the error is coming from.
