Forum Error

[p1a6u3]

Hello and thanks for taking time to read my inquiry.
I have done many searches for an answer to my problem and found somewhat similar answers but little if no directions as how to solve.
In my forum home there is a link in the drop down menu for checking "Todays Posts". When there is no new posts of course I get the message stating there are none.
However, when a new post or posts are made and the link is clicked it gives me this error.

Database error in vBulletin 3.6.4:

Invalid SQL:
SELECT searchid FROM search AS search WHERE userid = 1 AND searchhash = '42610ce97467a83d0ae5d628a7651d4f' AND orderedids

= '5' AND announceids = '' AND completed = 1;

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

From my searches I somewhat understand the error but dont know how to take action or where to look to edit. I am very confident and successful at following instructions, installing hacks etc etc.......my prob is where to look and how to fix. will running a specific query fix this, I am at a loss here please excuse me but I am very eager to learn.
If anyone out there can give me brief direct instructions I would be very grateful for your help.
Thank you in advance....
