UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Bug Reports Field 'O_Uid' doesn't have a default value

What version of MySQL are you trying to install on? This looks like an error when 6.5 is installed on a MySQL 5 database. 6.5.5 will only support MySQL 3 and 4. You'd need to install UBB.threads 7 in order to install on MySQL 5 if that's what you are running.
