[doubleclick]

This has been working fine for months, and now suddenly I'm getting hundreds of these errors everyday.

Database error in vBulletin 3.7.3:

Invalid SQL:

SELECT picture.pictureid, picture.userid, picture.extension, picture.idhash, picture.state, picture.fbbypass,
albumpicture.dateline, album.state AS albumstate, profileblockprivacy.requirement AS privacy_requirement,
picture.filedata, picture.filesize
FROM vbalbumpicture AS albumpicture
INNER JOIN vbpicture AS picture ON (albumpicture.pictureid = picture.pictureid)
INNER JOIN vbalbum AS album ON (albumpicture.albumid = album.albumid)
LEFT JOIN vbprofileblockprivacy AS profileblockprivacy ON
(profileblockprivacy.userid = picture.userid AND profileblockprivacy.blockid = 'albums')
WHERE albumpicture.albumid = 35 AND albumpicture.pictureid = 147;
