I recently had problems installing the code to my test server, and after discussing with Jamin, I decided to roll back to mySQL 4, the one posted on the mysql website. This did not fix the issue. I'm thinking it was InnoDB, I had the whole thing set up for MyISAM but it still wouldnt connect. So, I rolled back to an old version I happened to have. Everything works now, mySQL has to be version 4.0.16, 5 doesnt seem to work.
what problems were you having? i set up apache / php / mysql 5 on my desktop box so i could mess around with dragon knight without having to upload the files over and over again and its working fine for me. initially i had problems with the shoutbox, forums and news posting feature, but after commenting out the 'strict' mode in mysql config file (my.ini) its all running nicely.
