Causes Database Error with vB 4.1.1 and aMember

We use aMember to handle all of our subs. After updating to 4.1.1 we started to have database issues for new users trying to log into the forums.

Database error in vBulletin 4.1.1:

Invalid SQL:

SELECT forum.forumid, forum.lastpost, forum.lastposter, forum.lastposterid, forum.lastthread, forum.lastthreadid, forum.lasticonid, forum.threadcount, forum.replycount, forum.lastpostid, forum.lastprefixid, user.usergroupid, user.homepage, user.options AS useroptions, IF(userlist.friend = 'yes', 1, 0) AS isfriend

FROM forum AS forum

LEFT JOIN user AS user ON (user.userid = forum.lastposterid)
LEFT JOIN userlist AS userlist ON (userlist.relationid = user.userid AND userlist.type = 'buddy' AND userlist.userid = );

As you can see the issue is with this part of the code

AND userlist.userid = );

where the = is empty. After disabling Project Tools it worked like a charm again. So any ideas on how to solve this issue would be wonderful.

The strange thing with this query is why vB devs are using $vbulletin->userinfo['userid'] and $userid which is the same value?

I'm trying to see where it happens but can't reproduce.

Can you try this:

- Activate Project Tools product
- Uncheck every plugin related to Project Tools
- Enable 1 plugin at each time and to go page to the problematic page to see if the problem occurs
- When the first issue appears, give me the name of the latest plugin you activated

Thanks

PS: seems to be similar than http://www.vb-os.com/project.php?issueid=163

I posted a patch in my latest link, can you try it?

As I can't reproduce the problem but it seems the origin is the same... Thank you

I'll try the patch and see what happens. I had disabled all of my plugings and when I enabled only Project tools, any members created via aMember would not log in. So I'll test and report back
