SQL Error (Modification?)

[Nintendo-Daily]

I was wondering if anyone here has ever come across something like this. I get the error sporadically. Sometimes, my forums will function completely normal and other times, I get about 180+ email alerts with errors like:

Database error in vBulletin 3.8.4:

Invalid SQL:

SELECT
userfield.*, usertextfield.*, user.*, UNIX_TIMESTAMP(passworddate) AS passworddate, user.languageid AS saved_languageid,
IF(displaygroupid=0, user.usergroupid, displaygroupid) AS displaygroupid
,mgcugp.mgc_cb_evo_default_color,mgcugp.mgc_cb_evo _chanid
FROM user AS user
LEFT JOIN userfield AS userfield ON (user.userid = userfield.userid)
LEFT JOIN usertextfield AS usertextfield ON (usertextfield.userid = user.userid)
LEFT JOIN usergroup AS mgcugp ON (user.usergroupid=mgcugp.usergroupid)
WHERE user.userid = 175;

Whenever I do get the error, they all seem to have the "MGC" in there somewhere. I'm not sure if this is related to a certain modification that I have installed but I believe it might be.

Any help would in determining where this problem is stemming from would be greatly appreciated.

Thanks.
