Thanks so much!
But then I got an error for sig_thresshold and saw in the column of the error message I got that I was going to get another error for avatar_thresshold as well. So I looked even more than I did yesterday.
It occured to me there were two install.php files, one for the clean install and one for the upgrade. When I searched the one I used (for the upgrade) for the modoption column it couldn't find anything. That's when I thought that the upgrade php must have omitted entries figuring they were done by Zero Tolerance's hack. So I searched in the clean install file and found it, along with the other two I needed.
So for anyone getting that error message, I bet they were all people upgrading. Simply look in the clean install file and you'll find all the database queries you're missing which you can add manually through PHPMyAdmin.
