Once in a while a developer gets punished for programming habits. Well it's just happened to me, and the result is PHPFusion not being MySQL 5 compatible. Don't panic though, I do know where the problem lies (use of short inserts) and I will be updating all problematic MySQL inserts over the next few weeks. This issue should not affect main stream servers just yet, but of course I know some developers are using MySQL 5 on their own test servers.
