I am new to MyBB, but have hosted other sites before. I just made this forum today, and whenever a member tries to login, they get SQL Error 1054

So, no one can login, I can't access ACP. I can access my webhosts cPanel, though.

Have you used the Merge System?

I've tried, but it didn't work, so I removed it from the file manager.

Did you just delete it without running the "Cleanup" operation?

No, I ran the cleanup operation before deleting it.

I don't know if I do, and even if I did I can't access the ACP to disable it.

Open Filezilla or your chosen FTP client, and navigate to MyBB Root Folder/inc/plugins is loginconvert.php listed there?

hmm., somehow I missed that you do not have access to forum admin panel ..

Yes, there is:
hello.php
index.html
loginconvert.php
