Error trying to add a custom view

When trying to add a custom view, I get this error:

MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
    1054 - Unknown column 'custom_profile_fields' in 'field list'
Query:
    INSERT INTO adminviews (`uid`,`title`,`type`,`visibility`,`fields`,`conditions`,`custom_profile_fields`​,`sortby`,`sortorder`,`perpage`,`view_type`) VALUES ('14216','SPAMWOW','user','2','a:6:{i:0;s:8:\"username\";i:1;s:5:\"email\";i:2;s:10:\"lastactive\";i:3;s:7:\"postnum\";i:4;s:5:\"regip\";i:5;s:6:\"lastip\";}','a:14:{s:8:\"username\";s:0:\"\";s:5:\"email\";s:0:\"\";s:7:\"website\";s:0:\"\";s:3:\"icq\";s:0:\"\";s:3:\"aim\";s:0:\"\";s:5:\"yahoo\";s:0:\"\";s:3:\"msn\";s:0:\"\";s:9:\"signature\";s:0:\"\";s:9:\"usertitle\";s:0:\"\";s:11:\"postnum_dir\";s:12:\"greater_than\";s:7:\"postnum\";s:0:\"\";s:5:\"regip\";s:0:\"\";s:6:\"lastip\";s:0:\"\";s:6:\"postip\";s:0:\"\";}','a:3:{s:4:\"fid3\";a:1:{s:4:\"fid3\";s:3:\"N/A\";}s:4:\"fid1\";s:0:\"\";s:4:\"fid2\";s:0:\"\";}','regdate','desc','100','table')

I'm running MyBB v1.6.4

The field custom_profile_fields is not in the adminviews table, BTW.
