We are getting the following error message. Could any advise the problem and cure please.

Using version 1.8.19

MyBB has experienced an internal SQL error and cannot continue.

SQL Error:1054 - Unknown column 'r.username' in 'order clause'QueryELECT r.*, u.username, u.usergroup, u.displaygroup FROM mybb_threadsread r LEFT JOIN mybb_users u ON (u.uid = r.uid) WHERE r.tid = '2028' AND u.uid != '0' ORDER BY r.username ASC LIMIT 100

What were you doing when you received this error?

What plugins do you have installed?

I would imagine that mybb_users has the username column, not mybb_threadsread, so the order by clause should probably reference u.username instead of r.username. Your where clause should probably reference r.uid != 0 instead of u.ui.

I found a possible answer in one of the responses in this thread.

also search Google for "SQL Error:1054 - Unknown column 'r.username' in mybb"

your answer is one of the suggestions, you just have to find it.

Many thanks for your help and guidance.
It turned out to be a plugin in the end.
