MySQL Error 1064

I've been receiving a few emails from vBulletin that I'm getting some forum database errors. I see that the script is vbseo.php. Not too long ago I upgraded gXboxLive which uses field5 for Xbox Live Gamertags, but I wasn't quite sure how vbseo.php is causing the error. Any thoughts?

Code:

Database error in vBulletin 3.6.8:

Invalid SQL:
UPDATE vb3_userfield SET
                                       field5 = '
                                       WHERE userid = '158';

I don't think its a problem with vbseo... most likely the mod.

There's a cron task that runs something to update field 5, but its not getting passed in correctly.

its obviously missing the extra quote

field5 = ''

or even
field5 = 'something here'

Hello,

the actual script is cron.php, which is called by vbseo.php, so you should check your scheduled tasks to find which one causes the issue (vBSEO doesn't use similar sql queries).

Okay, I figured that this was probably caused by the cron job for the mod. I'll try disabling it and see what happens. Thanks for the replies.
