TOPIC: After submitting registration I get SQL Error

What is this error mean?

0 SQL=select SQL_CALC_FOUND_ROWS * from nkm_dtregister_event_detail where slabId=1 and member <= order by member desc LIMIT 0, 1

It happens right after submitting registration for event.

I should have responded sooner.
My problem is fixed now. There was a tiny, incremental change to the download file for the Joomla 3 update. I did have to delete the extension on my site and then re-install the new file.

I do believe that the ordering column was the issue fixed in the incremental update. I was having no luck ordering my fields before the update.
